Foreword

The National Standard Reference Data System is a Government-wide effort to provide for

the technical community of the United States effective access to the quantitative data of physical

science, critically evaluated and compiled for convenience, and readily accessible through a

variety of distribution channels. The System was established in 1963 by action of the President’s

Office of Science and Technology and the Federal Council for Science and Technology.

The responsibility to administer the System was assigned to the National Bureau of Standards

and an Office of Standard Reference Data was set up at the Bureau for this purpose. Since 1963,

this Office has developed systematic plans for meeting high-priority needs for reliable reference

data. It has undertaken to coordinate and integrate existing data evaluation and compilation

activities (primarily those under sponsorship of Federal agencies) into a comprehensive program,

supplementing and expanding technical coverage when necessary, establishing and maintaining

standards for the output of the participating groups, and providing mechanisms for the dissemination of the output as required.

The System now comprises a complex of data centers and other activities, carried on in Government agencies, academic institutions, and nongovernmental laboratories. The independent

operational status of existing critical data projects is maintained and encouraged. Data centers

that are components of the NSRDS produce compilations of critically evaluated data, critical re- views of the state of quantitative knowledge in specialized areas, and computations of useful

functions derived from standard reference data. In addition, the centers and projects establish

criteria for evaluation and compilation of data and make recommendations on needed modifications

or extensions of experimental techniques.

Data publications of the NSRDS take a variety of physical forms, including books, pamphlets,

loose-leaf sheets and computer tapes. While most of the compilations have been issued by the

Government Printing Office, several have appeared in scientific journals. Under some circumstances, private publishing houses are regarded as appropriate primary dissemination mechanisms.

The technical scope of the NSRDS is indicated by the principal categories of data compilation

projects now active or being planned: nuclear properties, atomic and molecular properties, solid state properties, thermodynamic and transport properties, chemical kinetics, colloid and surface

properties, and mechanical properties.

An important aspect of the NSRDS is the advice and planning assistance which the National

Research Council of the National Academy of Sciences-National Academy of Engineering provides.

These services are organized under an overall Review Committee which considers the program as a whole and makes recommendations on policy, long-term planning, and international collaboration.

Advisory Panels, each concerned with a single technical area, meet regularly to examine major

portions of the program, assign relative priorities, and identify specific key problems in need of

further attention. For selected specific topics, the Advisory Panels sponsor subpanels which

make detailed studies of users’ needs, the present state of knowledge, and existing data resources

as a basis for recommending one or more data compilation activities. This assembly of advisory

services contributed greatly to the guidance of NSRDS activities.

The NSRDS-NBS series of publications is intended primarily to include evaluated reference

data and critical reviews of long-term interest to the scientific and technical community.

Preface

This work was undertaken to meet the need for a critical assessment of the existing data for

electrical conductance, density and viscosity of inorganic compounds in the molten state. The

scope embraces the publications in the scientific literature to the current date (December, 1966):

while care was taken to be comprehensive, it is clear that there will be omissions and that the task

is therefore one to be continued and extended.

The results for some 174 compounds as single-salt melts are reported: no attempt was made

in the present effort to embrace the results for molten salt mixtures. With the exception of quaternary ammonium salts, an anion classification has been used for the presentation of the data: i.e.. Fluorides, Chlorides, Bromides, Iodides, Carbonates, Nitrites, Nitrates, Oxides, Sulfides, Sulfates,

and Miscellaneous.

The authors will be pleased to have additional studies directed to their attention.

Acknowledgments

This work was made possible in large part by financial support received from the Office of

Standard Reference Data, National Bureau of Standards, Washington, D.C., for the compilation

and critical evaluation of published literature in the general field of molten salts. The participation

Molten Salts: Volume 1, Electrical Conductance, Density, and Viscosity Data

G. J. Janz, F. W. Dampier, G. R. Lakshminarayanan, P. K. Lorenz, and R. P. T. Tomkins

Data on the electrical conductance, density and viscosity of single-salt melts were compiled from

a comprehensive search of the literature up to December 1966 and a critical assessment made of the compiled data. Recommended values were determined and are presented as functions of temperature in the form of equations and tables. The results for some 174 compounds as single-salt melts are reported; no attempt was made in the present effort to embrace the results for molten salt mixtures. Data are presented for fluorides,

chlorides, bromides, iodides, carbonates, nitrites, nitrates, oxides, sulfides, sulfates, and a miscel- laneous group.

Key Words: Data compilation, density, electrical conductance, molten salts, standard reference

data, viscosity.

Introduction

The critical assessment of the electrical con- ductance, viscosity, and density data of inorganic

compounds in the molten state (i.e., “single-salt

melts”) was undertaken to meet the need for

consistent sets of values for these properties.

With the exception of quaternary ammonium

slats, an anion classification has been used in this

compilation: i.e.. Fluorides, Chlorides, Bromides,

Iodides, Carbonates, Nitrites, Nitrates, Oxides,

Sulfides, Sulfates, and additional salts given as Miscellaneous. The order within each anionic

group is in the list of tables preceding section 6. Results are reported for some 174 compounds.

2.

Symbols and Units

The equations used to express the temperature

dependence of density, conductance, and viscosity

are as follows:

Density: Equivalent conductance:

p — a — bT A =A Ae~ EA/RT

Specific conductance:

k = a + bT

k= a + bT + cT1 k = a + bT+ cT2 + dTs

Viscosity:

r1 = Av EJ

HT

rj = a + bT + cT2 p = a + bT + cT2 + dT*

The symbols and units are: J = joule

cal = thermochemical calorie = 4. 1840J

T(°K) = temperature in degrees Kelvin, defined in

the thermodynamic scale by assigning

273.16 °K to the triple point of water (freezing point, 273.15 °K = 0 °C).

R = gas constant = 1.98717 calmol -1 deg -1 = 8.3143 J mol-1 deg -1

A = equivalent conductance (ohm"'cm- equiv -1

) A\= 'm ohm -1 cm2 equiv -1 Ea = in cal mol -1 k= specific conductance (ohm -1 cm -1

) p = density (g cm -3

) 7] = viscosity (cp)

Av = in cp

Ev = in cal mol-1

.

Preparation of Tables

The selection of the best values of the data for

the calculations was based on consideration of

different factors, such as: experimental techniques,

the number of measurements, the temperature

range, the deviations of the data from a fitted curve,

and the reliability of previous work from any one

center. In general the data of each investigation were evaluated by fitting linear, quadratic and

exponential equations by the method of least

squares; usually the equation with the smallest

standard deviation was selected as the best equation. In some cases, however, the data from several

laboratories have been combined for the preceding

analysis (see: discussions of the individual salts

(sec. 5)). The literature references are given as footnotes

in these tables. Where only one reference is underscored the data from that investigation has been

used to gain the best values. Where more than one

reference is underlined, the data from these sources were combined as reported in section 5, to gain

the best values. The tabulated best-values of

specific conductance, density, and viscosity, were

calculated using the equations listed with each

table (sec. 6). Equivalent Conductance — The equivalent con- ductance of a single-salt melt is defined by the

, .. A (Equivalent Weight) ^ x ^ j relation: A —

. 1 he tabulated

P

1
values of specific conductance and density were

used to gain the values of A (sec. 6), and the latter, to develop the exponential equations for equivalent

conductance.

Melting Points — The melting point reference is listed at the bottom of each table together with the

references for density, conductance and viscosity

(sec. 6). In some cases (e.g., Mgl2 , Gal2 ) the melting

point could only be indicated as less than a certain

temperature since the actual melting point was not

stated in the investigation (the lowest temperature

at which measurements were made on the liquid

melt).

Extrapolation Beyond the Experimental Temperature Limits — To calculate equivalent conductance

over the corresponding temperature range for which

specific conductance data were reported, extrapolation of the density data was necessary in some

cases. When this extrapolation exceeded a temperature range greater than 20°, the values are enclosed

in brackets (sec. 6). Estimation of Precision —

(i) Definitions: The standard deviation was computed by the expression:

S(AC -AC ) 2 n—p

where Xe and Xc are the experimental and calculated

values (from least squares equations), respectively,

for each temperature, n the number of data points,

and p the number of coefficients. The standard

deviation, s, is used as the index of precision (sec. 7). The percent precision (P.P.) is defined by:

P.P. = |x 100

where Z is the value of the physical property at the

“midpoint temperature” (i.e., the midpoint of the

temperature range over which the physical property

has been investigated). Thus, for LiCl the percent

precision would be simply

[0.00074 X 102 /6.215] = 0.012 percent.

Here 6.215 is the value of k at 980 °K (temperature

limits, 910 to 1050 °K; refer. Table 19, sec. 6). The percent precision values, stated in brackets,

normally follow immediately the precision values

e.g., 5 = 0.00074 (0.012%) for LiCl. The units for

precision are those of the physical property being

considered.

(ii) Computations: All computations were ef- fected with the digital computer facilities at Rensselaer Polytechnic Institute and Fortran IV programs.

The calculations with the quadratic equations, in

the majority of the cases, were taken to eight significant figures; the calculations with the exponential

and cubic equations, similarly to 14 significant fig- ures. The coefficients of these equations are stated

to more significant figures than is justified by the

accuracy in order that the equations may be used to

gain values within the limits of the precision of

the measurements.

4. Estimation of Uncertainty

Estimates of uncertainty were based primarily on comparisons of the departures of the experimental

results from the best values. Where this was impossible, the estimate of uncertainty was guided by

more qualitative factors. In all cases, consideration was also given to experimental techniques and

previous results from the respective laboratories.

The precision (i.e., the standard deviation was an

important consideration throughout this part of

the work.

The Percent Departure (P.D.) is defined by:

P.D. Experimental Value — Tabulated Value

Tabulated Value

100

and has been used to compare the results of different

investigators with the best values (sec. 6). The

Percent Departure analysis for three salts, KC1,

NaNCG, and KNO3 is illustrated in figures 1 to 3

respectively (sec. 5). Where an uncertainty statement is bracketed,

the brackets indicate that the estimate has been

based on minimal information.

5. Discussion

In this section the following information is given

for each compound: precision, estimated uncertainty, source of the temperature dependent equation,

and the departure values. For the data used to gain

the best equation, the details given are as follows:

literature reference, temperature range, number of

data points, and (for viscosity only) the experimental

technique. The maximum percent departure has

also been given, where possible (e.g., KC1 (fig. 1): the maximum percent departure between the values

of van Artsdalen [79] 1 and Winterhager [85] is 1.24(1112

The uncertainty statements in brackets, being

based on minimal information, are more qualitative

than the unbracketed values.

Lithium Fluoride

[Refer: Table 1, p. 42, for numerical values]

Four investigations of the specific conductance

for molten LiF have been reported [42. 83, 86, 88],

Compared to the data of Winterhager and Werner

[86] the results of van Artsdalen and Yaffe [83],

and Yim and Feinleib [88] show maximum depart- ures of 14.7 percent (1140 °K) and —4.1 percent

(1173 °K) respectively; the results of Ryschkewitsch

[42] show larger departures. It has been suggested

[198] that some experimental factors (e.g., possibly

1 Figures in brackets indicate the literature references on page 135.

2
a distortion of the potential probe arrangement) led

to systematically high values in the van Artsdalen

measurements. The work of Winterhager and

Werner [86] appears the most thorough; their

data (1148.2 to 1310 °K, 9 points) were selected.

Using the quadratic equation for specific conduct- ance the precision is 5 = 0.0237 (0.264%). The uncertainty of the specific conductance values is estimated to be about 12 percent.

The exponential equation expresses the tabulated

values of equivalent conductance with a precision

5 = 0.303 (0.23%).

Three density studies have been reported [25,

81, 83]. The estimated uncertainty of the density

values, based on the van Artsdalen studies [83], is 0.5 percent. The maximum departure between the

densities of van Artsdalen and Jaeger [25] is 0.5

percent (1141.7 °K). The studies of Schinke ~nd

Sauerwald [81] were to establish the volume change

on fusion.

Sodium Fluoride

[Refer: Table 2, p. 42, for numerical values]

Five investigations of the specific conductance for

molten NaF have been reported [31, 46, 67, 86, 88].

The tabulated values were calculated from the data

of Winterhager and Werner [86] (1276.2 to 1411.2 °K,

8 points). Using the linear equation for specific

conductance the precision is 5 = 0.0089 (0.17%). The

maximum departure between the data of Winterhager [86] and Yim and Feinleib [88] is 3.1 percent

(1270 °K). The uncertainty of the specific conductance values is estimated to be about 3.5 percent.

The exponential equation expresses the tabulated

values of equivalent conductance with a precision

5 = 0.119 (0.10%).

Of the two density investigations [25, 31], the

results of Jaeger [25] were selected to generate

the tabulated values; the information was insufficient

for an estimate of accuracy.

Potassium Fluoride

[Refer: Table 3, p. 43, for numerical values]

Eight investigations of the specific conductance

for molten KF have been reported [26, 31, 42, 73,

83, 86, 88, 198]. The tabulated values were calculated from the data of Winterhager and Werner

[86] (1132.2 to 1285.2 °K, 12 points). Using the

linear equation for specific conductance the precision is 5 = 0.0201 (0.526%). The study of specific

conductance for KF by Bredig and Bronstein [198] was limited to one temperature (1178.2 °K). Comparison of this value (3.77 11 _1 cm-1

) with that of

Winterhager and Werner shows the departure to be 1.85 percent. The results of the other investigators show larger departures. The uncertainty of

the specific conductance values is estimated to be

about 12 percent.

The exponential equation expresses the tabulated

values of equivalent conductance with a precision

5 = 0.188 (0.16%).

Of the three density studies [26, 81,83], the in- vestigation of van Artsdalen [83] appears most

thorough. The maximum departure between the

density data of van Artsdalen and Jaeger and

Kapma [26] is 0.9 percent (1140 °K). The study of

Schinke and Sauerwald [81] were to establish the

volume change on fusion. The uncertainty of the

density values is judged to be about 0.6 percent.

Cesium Fluoride

[Refer: Table 4, p. 43, for numerical values]

Two investigations of the specific conductance

for molten CsF have been reported [182, 83]. The

tabulated values were calculated from the data of

Bronstein, Dworkin, and Bredig [182] (1010.2 to 1125.2 °K, 6 points). Using the linear equation for

specific conductance the precision is 5 = 0.0456

(1.73%). The maximum departure between the

results of Bredig [182] and Yaffe and van Artsdalen [83] is 34 percent (1050 °K). The uncertainty

of the specific conductance values is estimated to be about 5 percent.

The exponential equation expresses the tabulated

values of equivalent conductance with a precision

5 = 0.118(0.097%).

Of the two density studies [25, 83], the data of van Artsdalen [83] were selected to calculate the

tabulated values. The maximum departure between

the densities reported by Jaeger [25] and van Artsdalen [83] is 1.1 percent (1041.9 °K). The uncertainty of the density values is judged to be about

0.8 percent.

Beryllium Fluoride

[Refer: Table 5, p. 44, for numerical values]

The tabulated values of specific conductance for

molten BeF2 were obtained from the data of Mackenzie [143] (973 to 1173 °K, 6 points). Since the

least squaring to quadratic, cubic and exponential

equations was unsatisfactory, the values were

gained graphically. No attempt to estimate the

accuracy of the specific conductance values was

made.

Two investigations of the viscosity have been

reported [143, 225]. The tabulated values were

calculated from the data of Moynihan and Cantor

[225] (846.9 to 1252.2 °K, 25 points, rotating cylinder

viscometer). The exponential equation expresses

the data of Moynihan and Cantor with a precision

5 = 3.08X 106 (2.77%). The uncertainty of the

viscosity values is judged to be about 3.0 percent.

The viscosities of the second study (Mackenzie

[143], restricted falling ball technique), show departures of about 8.0 percent from those of Moynihan

and Cantor.

Magnesium Fluoride, Caleium Fluoride,

Strontium Fluoride, Barium Fluoride,

Lanthanum (III) Fluoride, and Cerium

(III) Fluoride

[Refer: Tables 6 to 11, pp. 44 to 45, for numerical

values]

The tabulated values of density for molten MgF2 , CaF2 , SrF2 , BaF2 , LaF3 , and CeF3 were calculated

from the data of Kirshenbaum, Cahill, and Stokes

[95]. The maximum departure between the density values of Mashovetz [197] and Kirshenbaum

[95] is 0.4 percent for CaF2 . The uncertainty of

density values is estimated to be about 0.5 percent

for CaF2 and (1.0%) for the other five fluorides.

Thorium (IY) Fluoride and Uranium (IV)

Fluoride

[Refer: Tables 12 and 13, p. 46, for numerical values]

The tabulated values of density for molten ThF4 and UF4 were calculated from the data of Kirshenbaum and Cahill [167]. The uncertainty of the

density values is estimated to be about (1%).

Manganese Fluoride, Copper (II) Fluoride,

Silver Fluoride, Zinc Fluoride, and Lead

Fluoride

[Refer: Tables 14 to 18, pp. 46 to 47]

The tabulated values of the specific conductances

for molten MnF2 , CuF2 , AgF, ZnF2 , and PbF2 were

calculated from the graphical data of Winterhager

and Werner [86], The number of data points interpolated from the Winterhager graphs, the cor- responding temperature ranges and the best equation are as follows:

MnF2 4 points, 1223—1273 °K, linear equation

CuF2 6 points, 1233-1370 °K, linear equation

AgF 6 points, 773—923 °K, linear equation

ZnF2 4 points, 1173-1223 °K, linear equation

PbF2 7 points, 1123-1273 °K, linear equation.

The uncertainty of the specific conductance

values is estimated to be about (20%).

Lithium Chloride

[Refer: Table 19, p. 47, for numerical values]

Nine investigations of the specific conductance

for molten LiCl have been reported [33, 42, 44,

45, 55, 62, 66, 79, 85]. The specific conductance

values of van Artsdalen and Yaffe [79] (917.1 to 1056.5 °K; 7 of the 9 reported temperatures omitting

896.0 and 907.6 °K) and two values from Edwards

[62] (920.2 and 940.2 °K) were used to develop the

quadratic equation. Using the quadratic equation

for specific conductance the precision is 5 = 0.00074

(0.012%). The maximum percent departures of the

specific conductance values of various investigators from the combined data of van Artsdalen

[79] and Edwards et al. [62] , are as follows: Bloom

et al. [66], 3.2 (910 °K); Biltz and Klemm [33], 0.8

(954.2 °K); Grothe [55], 0.3 (973.2 °K): Winterhager and Werner [85], —0.7 (961.2 °K) and Karpachev et al. [44], —3.0 (910 °K). The results of

Ryschkewitsch [42] show larger departures. The

uncertainty of the specific conductance values is estimated to be about 0.7 percent. Considerable

corrosion of the cell (above 1056 °K) was noted by

van Artsdalen.

The exponential equation expresses the tabulated

values of equivalent conductance with a precision

5 = 0.0847 (0.048%).

Of the seven sets of density data [3, 25, 55, 62,

66, 79, 81] the most thorough studies appear to be

those of van Artsdalen [79] and Bloom [66]. The

uncertainty of the tabulated densities, calculated

from the van Artsdalen data [79] is estimated to be about 0.2 percent. Compared to the density data

of van Artsdalen, the results of Bloom et al. [66]

,

Brunner [3], Edwards et al. [62], Jaeger [25] and

Grothe [55] show maximum departures of 0.2 percent (900 °K), —0.2 percent (1050 °K). —0.3 percent

(1050 °K), —0.4 percent (913 °K) and —0.4 percent

(1050 °K) respectively.

10, 27, 33, 42, 49, 52, 55, 62, 63, 71, 79, 82, 85,

26 reported temperatures, omitting 1075.5 and

1077.8 °K) were used to develop the tabulated val- ues. Using the quadratic equation for specific con- ductance the precision is 5 = 0.00164 (0.043%).

Compared to the data of van Artsdalen the results

of Ryschkewitsch [42], and Edwards et al. [62],

show maximum departures of —0.6 percent (1093

°K) and 0.8 percent (1273 °K) respectively; the

(1080 °K), —0.4 percent (1111 °K) and 0.6 percent

(1290 °K) respectively; the results of Bloom et al. [66] and Jaeger [25] show larger departures. The

Bockris [123] is about 0.4 percent over the range

1053.2 to 1198.2 °K. Van Artsdalen [79] and

Crook [123] both used well established a-c con- ductance techniques (0.5 to 20 kc/sec); the results

of Duke [124] were gained with a d-c technique. The

results of Buckle and Tsaoussoglou [125a], gained

with a new a-c technique (10 to 100 kc/sec) are lower than the van Artsdalen data by about 0.8

percent. The results of the other investigators show

Manganese (II) Chloride

[Refer: Table 41, p. 55, for numerical values]

Two investigations of the specific conductance

for molten MnCU have been reported [85, 192]. The

tabulated values were calculated from the data of

Murgulescu and Zuca [192] (923.2 to 1123.2 °K, 5

points). Using the quadratic equation for specific

conductance the precision is 5 = 3.66 • 10~ 4 (0.022%).

Comparison of the data of Murgulescu [192] and

Winterhager and Werner [85] shows the maximum

departure to be about 27 percent (1128.2 °K). The

uncertainty of the specific conductance values is estimated to be about 20 percent.

The exponential equation expresses the tabulated

values of equivalent conductance with a precision

5 = 0.265 (0.59%).

The density data of Murgulescu [192] were used

to calculate the tabulated values; no estimate of

accuracy was attempted owing to the limited

information.

[Refer: Table 42, p. 55, for numerical values]

The tabulated values of viscosity for molten TiCb

have been calculated from the data of Toropov [204]

(293 to 333 °K, 3 points, capillary viscometer). The

exponential equation expresses the data of Toropov

with a precision 5 = 0.0095 (1.39%). No estimate of

accuracy was attempted owing to the limited

information.

Copper (I) Chloride

[Refer: Table 43, p. 56, for numerical values]

Five investigations of the specific conductance for

molten CuCl have been reported [33, 35, 85, 189,

212]. The tabulated values were calculated from the

data of Grantham and Yosim [189] (746.2 to 1430.2

°K, 19 points). Using the cubic equation for specific

conductance the precision is 5 = 6.40 • 10~ 3 (0.16%).

This cubic equation can be used to gain values of

specific conductance (within 6%) in the range 700 to

9
740 °K. Grantham [189] has reported a specific con- ductance maximum at 1123 °K. Compared to the

data of Grantham the results of Klemm and Biltz

[33], and Winterhager and Werner [85] show maximum departures of — 5.5 percent (740 °K), and 5.1

percent (950 °K) respectively. The uncertainty of the

specific conductance values is estimated to be

about 5 percent.

The exponential equation expresses the tabulated

values of equivalent conductance with a precision

5 = 0.968(0.84%).

The data of Klemm [36] were used to calculate the

densities; no estimate of accuracy was attempted

owing to the limited information.

The tabulated values of viscosity were calculated

from the data of Karpachev and Stromberg [47]

(773.2 to 973.2 °K, 5 points, oscillating ball technique). The cubic equation expresses the data with

a precision 5 = 0.00069 (0.037%). The uncertainty

of the viscosity values is estimated to be about

(2.0%).

Silver Chloride

[Refer: Table 44, p. 56, for numerical values]

Eight investigations of the specific conductance

for molten AgCl have been reported [1, 10, 21, 23,

60, 72, 100, 166, 202, 212]. The tabulated values were calculated from the quadratic specific con- ductance equation of Bell and Flengas [166] (753

to 1013 °K). The precision reported by Flengas is 5 = 0.0035 (0.082%). The maximum percent departures between the specific conductance values of

Bell and Flengas [166] and the other investigators are as follows: Spooner and Wetmore [60], 0.4

percent (773.2 °K); Doucet and Bizouard [100],

1.1 percent (873.2 °K); Arndt and Gessler [10],

4.4 percent (973 °K); Tubandt and Lorenz [21], — 3.8 percent (873 °K); Lorenz and Hochberg [23],

2.6 percent (873 °K); and Harrap and Heymann

[72], —2.7 percent (873 °K). The uncertainty of

the specific conductance values is estimated to be

about 0.7 percent.

The exponential equation expresses the tabulated values of equivalent conductance with a precision 5 = 0.279 (0.21%).

Of the five density studies [22, 54, 60, 81, 166,

212] the data of Flengas [166] were selected to cal- culate the tabulated values. Compared to the density data of Flengas [166] the results of Spooner

and Wetmore [60], Lorenz and Hochberg [22],

and Boardman, Dorman, and Heymann [54], show

maximum departures of 0.2 percent (743 °K), — 0.8

percent (901 °K), and —1.1 percent (900 °K) respectively. The studies of Schinke and Sauerwald [81] were to establish the volume change on fusion.

The estimated uncertainty of the density values is about 0.1 percent.

Two investigations of the viscosity have been

reported [24, 72]. The tabulated values were

calculated from the data of Harrap and Heymann

[72] (723.2 to 973.2 °K, 10 points, vertical capillary

viscometer). The cubic equation expresses the data

of Harrap and Heymann with a precision s = 0.0033

(0.19%). The uncertainty of the viscosity values

is estimated to be about 1.5 percent.

The results of the second study (Lorenz and

Hochberg [24], oscillating disk technique) are

consistently lower than those of Harrap and Heymann (e.g., -2.7%, 876.2 °K: -6.4%, 942.2 °K).

Zinc Chloride

[Refer: Table 45, p. 57, for numerical values]

Five investigations of the specific conductance for

molten ZnCf> have been reported [33, 87, 94, 98,

189]. The tabulated values were calculated from the

data of Bockris et al. [94] (593.3 to 969.7 °K). To

cover the entire range it was necessary to generate

three quadratic equations: the temperature range,

the number of data points, and the precision appropriate to this subdivision are as follows:

593.3 to 672.5 °K, 7 points, s = 4.66 x 10~ 4 (6.6%);

672.5 to 824.7 °K, 10 points, 5 = 8.38 X 10-4 (1.25%);

824.7 to 969.7 °K, 13 points, 5 = 1.60 X 10- 3 (0.53%).

Comparison of the data of Bockris [94] and Grantham and Yosim [189] in the low temperature region

(593.3 to 672.5 °K) shows the maximum departure

to be 42 percent (633 °K). The uncertainty of the

specific conductance values for this region is esti- mated to be about 30 percent. The maximum departure between the data of Bockris [94] and Duke and

Fleming [87] (in the range 672.5 to 824.7 °K) is — 5.6

percent (748 °K). In the high temperature range

(824.7 to 969.7 °K) comparison of the results of

Bockris [94] and Grantham [189] shows the maximum departure to be 3.94 percent (937.2 °K). The

uncertainty of the specific conductance values in

the region 672.5 to 969.7 °K is estimated to be about

5 percent.

For temperatures above 960 °K values of specific

conductance may be gained from the following

quadratic equation (5=0.011 (1.8%)) based on the

data of Grantham [189] (937.2 to 1136.2 °K, 5 points):

k= 1.50344-4.54126 • 10~ 3 r + 3.55485 • lO-T2

. The three exponential equations express the

tabulated values of equivalent conductance with

the precisions 5 = 0.040 (18%) (593.3 to 672.5 °K);

5 = 0.062 (3.3%) (672.5 to 824.7 °K); 5 = 0.080 (0.94%)

(824.7 to 969.7 °K) respectively.

Of the seven investigations of density [36, 40.

56, 87, 91, 98, 113] the results of Mackenzie and

Murphy [98] were selected to calculate the tabulated values. The density values of Mackenzie [98] are in agreement with those of Klemm [36] to within

(0.3%). Compared to the data of Mackenzie, the

results of Duke and Fleming [87], Wachter and

Hildebrand [40] and Ellis and Smith [91] show

maximum departures of —0.2 percent (866 °K),

10
— 0.5 percent (823.9 °K) and —1.6 percent (934 °K)

respectively.

The tabulated values of viscosity were obtained

from the data of Mackenzie and Murphy [98] (593.2

to 673.2 °K, 5 points, restricted falling ball technique). Since the least squaring to exponential,

quadratic and cubic were poor, it became necessary

to obtain the tabulated values from a smooth curve

of the experimental data.

Six investigations of the specific conductance of

25 points). Using the quadratic equation for specific

conductance the precision is 5 = 0.000149 (0.007%).

Compared to the data of Bockris, the results of

Bloom and Heymann [51], Bloom and Knaggs [66]

and Aten [19] show departures of — 0.3 percent

(873 °K), 0.8 percent (1000 °K) and —0.8 percent

(853 °K) respectively; the results of the other investigators show larger departures. The uncertainty of

departure between the density values of Bloom [66]

and Boardman [54] is 0.3 percent (850 °K) while that

between the tabulated values and the values of

Lorenz, Frei, and Jabs [15] is 1.3 percent (870 °K).

[47, 53]. The tabulated values of viscosity were

calculated from the data of Bloom, Harrap, and

capillary viscometer). The exponential equation

expresses the data of Bloom, Harrap, and Heymann

with a precision 5=0.0075 (0.36%). The uncertainty

of the viscosity values is estimated to be about 1.5

percent.

Of the two density studies [66, 110] the data of

Bloom et al. [66] were selected to calculate the

tabulated values. The maximum departure between

the densities reported by Bloom [66] and Ubbelohde

[110] is 0.99 percent (720 °K). The uncertainty of

the density values is judged to be about 1.0 percent.

Two investigations of the viscosity for this salt have been reported [110, 125c, 207]. The tabulated

values were calculated from the data of Protsenko,

Protsenko, and Razumovskaya [207] (563 to 613

°K, 6 points, capillary viscometer). The cubic equation expresses the data with a precision 5 = 0.0187

(0.70%). The uncertainty of viscosity values is con- sidered to be about 1.0 percent.

The results of the second study (Frame, Rhodes,

Ubbelohde [110, 125c] capillary viscometer) are consistently lower than those of Protsenko (e.g.,

4.0%, 572.7 °K; 1.4%, 583.5 °K).

Potassium Nitrite

[Refer: Table 112, p. 87, for numerical values]

The tabulated values of specific conductance for

molten KNOo were calculated from the data of

Protsenko, Protsenko, and Razumovskaya [207]

(713 to 743 °K, 4 points). Using the quadratic equation for specific conductance the precision is 5 = 4.70 • 10 -4 (0.058%). The uncertainty of the specific conductance values is estimated to be about

(6%).

The exponential equation expresses the tabulated

values of equivalent conductance with a precision

5 = 0.0617(0.075%).

The data of Protsenko and Malakhova [173] were

used to calculate the densities; no estimate of ac- curacy was attempted owing to the limited information.

Two investigations of the viscosity have been

reported [110, 125c, 207, 208] . The tabulated values were calculated from the data of Frame, Rhodes,

and Ubbelohde [110, 125c] (686.8 °K to 725.4 °K,

9 points, capillary viscometer). The cubic equation

expresses the data of Ubbelohde with a precision

5 = 0.0055 (0.30%). The uncertainty of the viscosity

values is judged to be about 1.5 percent.

The viscosities of the second study (Protsenko,

Protsenko, and Razumovskaya [207] and Protsenko

and Shokina [208], capillary viscometer), are consistently lower than those of Ubbelohde (e.g., 5.7%,

713 °K).

Rubidium Nitrite

[Refer: Table 113, p. 87, for numerical values]

The tabulated values of specific conductance for

molten RbNC>2 were calculated from the data of

Protsenko, Protsenko, and Razumovskaya [207]

(712 to 758 °K, 7 points). Using the quadratic equation for specific conductance the precision is 5 = 0.0025 (0.25%). The uncertainty of the specific

conductance values is estimated to be about (6%).

The tabulated values of viscosity have been cal- culated from the data of Protsenko, Protsenko, and

Razumovskaya [207] (712 to 758 °K, 7 points,

capillary viscometer). The exponential equation

expresses the data with a precision 5 = 0.0054

(0.28%). The uncertainty of the viscosity values

is considered to be about (1.0%).

Cesium Nitrite

[Refer: Table 114, p. 87, for numerical values]

The tabulated values of specific conductance for

molten CsN02 were calculated from the data of

Protsenko, Protsenko, and Razumovskaya [207]

(688 to 739 °K, 9 points). Using the linear equation for

specific conductance the precision is 5 = 7.41 • 10-4 (0.096%). The uncertainty of the specific conduct- ance values is estimated to be about (6%).

The tabulated values of viscosity have been cal- culated from the data of Protsenko, Protsenko,

and Razumovskaya [207] (688 to 739 °K, 9 points,

capillary viscometer). The cubic equation expresses

the data with a precision 5 = 0.0080 (0.39%). The

uncertainty of the viscosity values is considered to be about (1.0%).

Barium Nitrite

[Refer: Table 115, p. 87, for numerical values]

The tabulated values of specific conductance for

molten Ba(N02)2 were calculated from the data of

Protsenko and Shokina [185] (553.2 and 573.2 °K,

2 points). Only a linear equation for specific con- ductance was used to calculate the values. The

uncertainty of the specific conductance values is estimated to be about (6%).

The exponential equation expresses the tabulated values of equivalent conductance with a precision 5 = 0.0601 (0.80%).

The data of Protsenko and Malakhova [173] were

used to calculate the densities; no estimate of accuracy was attempted owing to the limited information.

Lithium Nitrate

[Refer: Table 116, p. 88, for numerical values]

Five investigations of the specific conductance

for molten LiNCL have been reported [26, 93, 116,

194, 224]. The tabulated values were calculated

from the quadratic equation reported by King and

Duke [116] (558 to 653 °K). Using the quadratic

equation the precision is 5 = 0.001 (0.083%). Compared to the data of King and Duke [116], the re- sults of de Nooijer and Ketelaar [224] , Doucet and

Bizouard [93], Cowen and Axon [194] and Jaeger

and Kapma [26] show maximum departures of

0.4 percent (631 °K), —0.9 percent (579.8 °K), —0.8

percent (573 °K) and 0.9 percent (640 °K) respectively. The uncertainty of the specific conductance

values is estimated to be about 0.4 percent.

The exponential equation expresses the tabulated

values of equivalent conductance with a precision

5 = 0.326 (0.60%).

Three density studies have been reported [26,

180, 224]. The density data of Jaeger and Kapma

[26] were selected to generate the tabulated values.

The more recent results of Smith and Petersen

[180] and de Nooijer and Ketelaar [224] are in

good agreement with the data of Jaeger, the agreement being better than 0.1 percent over the entire

temperature range.

Four investigations of the viscosity have been

reported [5, 38, 139, 228]. The results of Dantuma

[38] (533.2 to 702.2 °K, 37 points, oscillating ball

technique) appear to be the most thorough. The

more recent investigation of Murgulescu and Zuca

[139] lacks details on the preparation, purity

and melting point of the salt. Protsenko and

Razumovskaya [228] reported a higher (5 degrees)

melting point for LiNO:? and lower melting points

for the other alkali nitrates (except KNO:i ), silver

nitrate and thallous nitrate than the generally

accepted values; this may imply an error in thermometry and/or impurities in the salts. Goodwin

and Mailey [5] reported a lower melting point for

LiNO.j.

Judging from the above considerations and in

view of the most precise work for the other nitrates

(NaNO.j and KNCG) the data of Dantuma were

selected to calculate the tabulated values. Using

the cubic equation for viscosity the precision is

5 = 0.1143 (3.12%). The uncertainty of the viscosity

values is estimated to be about 3.5 percent.

The investigator, reference, experimental method

and the maximum percent departure are as follows:

Goodwin and Mailey [5], vertical capillary, —24

percent; Murgulescu and Zuca [139]. oscillating

ball, — 14 percent; and Protsenko and Razumovskaya

[228], vertical capillary, — 23 percent.

Sodium Nitrate

[Refer: Table 117, p. 88, for numerical values]

Ten investigations of the specific conductance

for molten NaNO.3 have been reported [7, 26, 27,

61, 66, 71, 75, 93, 192, 224], The tabulated values were calculated from the data of Byrne et al. [61]

(583.2 to 643.2 °K, 7 points) and Lorenz and Kalmus

[7] (591.2 to 691.2 °K, 11 points). Using the linear

25
equation for specific conductance the precision is 5 = 7.83 • 10-4 (0.06%). Compared to the data of

Lorenz [7] the results of Byrne [61], de Nooijer and

Ketelaar [224] and Sandonnini [27] show maximum

departures of 0.4 percent (633 °K), 0.6 percent (694

°K) and 0.9 percent (623 °K) respectively; the results

of the other investigators show larger departures.

The uncertainty of the specific conductance values

is estimated to be about 1.0 percent.

The exponential equation expresses the tabulated values of equivalent conductance with a precision 5 = 0.0160 (0.028%).

Of the four density studies [15, 26, 61, 66], the

data of Bloom et al. [66] and Byrne [61] were se- lected to generate the tabulated values. The density equation has been calculated from the average

of the coefficients of the linear density equations

reported by Bloom [66] and Byrne [61]. Compared

to the combined data of Bloom [66] and Byrne

[61] the results of Jaeger [26] and Lorenz, Frei, and

Jabs [15] show maximum departures of 0.7 percent

(700 °K) and 0.1 percent (673 °K) respectively. The

uncertainty of the density values is judged to be

about 1 percent.

Six investigations of the viscosity have been re- ported [5, 8, 12, 38, 102, 228]. The tabulated values were calculated from the data of Dantuma [38] (589.2

to 731.2 °K, 33 points, oscillating ball technique).

The exponential equation expresses the data of

Dantuma with a precision 5 = 0.0284 (1.41%). The

departures of various viscosity determinations of

NaN03 from the values of Dantuma are presented

in figure 2. The estimated uncertainty of the viscosity values is about 1.5 percent.

Figure 2. Comparison of percent departure of the data of

various investigators with the Dantuma viscosity data for NaN03 Base line-Dantuma [38] a Goodwin and Mailey [5] o Lorenz and Kalmus [8] o Fawsitt [12] v Murgulescu and Zuca [102] 1 he results of Protsenko and Razumovskaya [228] show de- partures of up to —0.4 percent from the base line.

The investigator, reference, experimental method,

and the maximum percent departure from the values

of Dantuma are as follows: Goodwin and Mailey [5],

vertical capillary, —4.3 percent; Lorenz and Kalmus [8], horizontal capillary, + 3.9 percent; Fawsitt

[12], oscillating disk, +3.6 percent; Murgulescu

and Zuca [102], oscillating ball, —2.1 percent; and

Protsenko and Razumovskaya [228], vertical capillary. — 0.4 percent.

The uncertainty of the viscosity of NaN03 could

be greater than 3.0 percent at higher temperatures

due to partial decomposition of the melt. All the

investigations of NaN03 were carried out in a normal atmosphere; the agreement was good between the different methods. If decomposition oc- curred in the melt it does not appear significantly

greater in any one method. While molten NaN03 undergoes decomposition at elevated temperatures

(>660 °K) it has been generally used as a calibration fluid for high temperature viscosity studies.

Potassium Nitrate

[Refer: Table 118, p. 89, for numerical values]

Twelve investigations of the specific conduct- ance for molten KN03 have been reported [7, 20.

26, 27, 66, 84, 92, 116, 192, 193, 194, 224]. The

tabulated values were calculated from the data of

Aten [20] (613.2 to 773.2 °K, 9 points) and Bloom

et al. [66] (800 to 880 °K, 5 points, gained from

Bloom’s exponential equation at 20 deg intervals).

Using the quadratic equation for specific conduct- ance the precision is 5 = 0.00369 (0.37%). Compared

to the data of Aten [20] and Bloom et al. [66]

,

the results of King and Duke [116], Sandonnini

[27], and Lorenz and Kalmus [7] show maximum

departures of 0.3 percent (620 °K), —0.2 percent

(673 °K) and —1.6 percent (686 °K) respectively.

The departures of the various specific conductance

determinations of KN03 from the tabulated values

are in figure 3A. The uncertainty of the tabulated

specific conductance values is estimated to be

about 0.8 percent.

Values of specific conductance (5 = 8. 10“+ 0.1%)

for the temperature range 623 to 698 °K should be

calculated from the following equation reported

by Duke [116]: k = -2.4566 + 6.72893 • 10-3 r — 2.7583 • lO -6 /

12

. The uncertainty of the specific

conductance values calculated from the equation

of Duke [116] is estimated to be about 0.3 percent.

The data of Duke [116] appears highly suitable for a high temperature calibration reference standard.

The exponential equation expresses the tabulated

values of equivalent conductance with a precision

5 = 0.0832 (0.14%).

Of the ten density studies [15, 26, 38, 66, 84,

173, 177, 184, 192, 210] the data of Bloom et al. [66] were selected to calculate the tabulated values.

Compared to the density data of Bloom et al. [66]

the results of other investigators are as follows:

Dantuma [38], —0.2 percent (660 °K); Smith and

and Polyakov and Berul [184], — 0.4 percent

(713 to 773 °K). The uncertainty of the density values

is judged to be about 0.2 percent.

Eight investigations of the viscosity have been re- ported [5, 8, 12 , 38, 57, 102, 107, 228]. The tabulated

values of viscosity were calculated from the data

of Dantuma [38] (671.2 to 815.2 °K, 35 points, oscillating ball technique). The cubic equation expresses

the data with a precision 5 = 0.0234 (1.38%). The

departures of the various viscosity determinations

of KNO3 from the values of Dantuma are presented

in figure 3B. The uncertainty of the viscosity data

is estimated to be about 1.5 percent.

The investigator, reference, experimental method,

and the maximum percent departure from the values

of Dantuma are as follows: Goodwin and Mailey

[5], vertical capillary, —2.9 percent; Lorenz and

Kalmus [ 8 ], horizontal capillary, +2.5 percent;

Fawsitt [ 12 ], oscillating disk, — 2.8 percent;

Ogawa [57], restricted falling sphere, —2.4 per- cent; Murgulescu and Zuca [ 102 ], oscillating ball, — 1.4 percent; Janz and Saegusa [107], oscillating

hollow sphere, —0.9 percent; and Protsenko and

Razumovskaya [228], vertical capillary, +0.5

percent.

The uncertainty of the viscosity of KNO3 could

be greater than 2.7 percent at higher temperatures

due to partial decomposition of the melt. All the

investigations of KN03 were carried out in a normal

atmosphere; the agreement was good between the

different methods. Hence if decomposition occurred

in the melt, it does not appear significantly greater

in any one method. While molten KN03 decomposes

at elevated temperature (>780 °K), it has been

used as a high temperature viscosity calibration

fluid.

Rubidium Nitrate

[Refer: Table 119, p. 89, for numerical values]

Two investigations of the specific conductance

for molten RbN03 have been reported [26, 224],

The tabulated values were calculated from the

data of Jaeger and Kapma [26] (592.0 to 766.2 °K,

12 points). Using the quadratic equation for specific conductance the precision is s = 0.00153

(0.25%). The uncertainty of the specific conduct- ance values is estimated to be about 6 percent.

De Nooijer and Ketelaar [224] report results for

the specific conductance for the temperature range

588.6 to 724.0 °K (10 points) which fall within the

limits of the above accuracy estimate.

The exponential equation expresses the tabulated

values of equivalent conductance with a precision

5 = 0.226 (0.57%).

The density data of Jaeger and Kapma [26] were

used to calculate the tabulated values; no estimate

of accuracy was attempted owing to the limited

information.

Two investigations of the viscosity have been

reported [139, 228], The tabulated values were calculated from the data of Murgulescu and Zuca [139]

(623 to 698 °K, 5 points, oscillating ball technique).

The cubic equation expresses the data with a precision 5 = 0.00717 (0.25%). The uncertainty of the

viscosity values is estimated to be about 1.0 percent.

The results of the second study (Protsenko and

Razumovskaya [228], vertical capillary viscometer),

are consistently lower (about 7%) than those of

Murgulescu and Zuca. Protsenko reported a lower

melting point (158 °K) for RbNO:! than the generally

accepted value (589 °K).

Three investigations of the specific conductance

for molten CsNO,3 have been reported [26, 84,

224] . The tabulated values were calculated from

the linear equation reported by van Artsdalen [84]

for the temperature range of 688.2 to 764.2 °K. No

precision was reported. Compared to the data of van Artsdalen the results of de Nooijer and Ketelaar

[224] and Jaeger and Kapma [26] show maximum

departures of 0.5 percent (735 °K) and — 2.0 percent

(745.9 °K) respectively. The uncertainty of the specific conductance values is estimated to be about

0.6 percent.

The exponential equation expresses the tabulated

values of equivalent conductance with a precision

5 = 0.00503 (0.019%).

Of the two density studies [26, 84] the data of van Artsdalen [84] were selected to calculate the

tabulated values. The maximum departure between

the densities reported by van Artsdalen [84] and

Jaeger [26] is 0.15 percent (780 °K). The uncertainty of the density values is judged to be about

0.15 percent.

Two investigations of the viscosity have been

reported [ 139, 228]. The tabulated values were

calculated from the data of Protsenko and Razumovskaya [228] (698.2 to 776.2 °K, 15 points, vertical

capillary viscometer). Using the cubic equation

for viscosity the precision is s = 0.0033 (0.18%).

The uncertainty of the viscosity values is judged

to be about 4.5 percent.

The study of Murgulescu and Zuca [138] (oscillating ball method) is limited to one temperature; their

value (2.43 cp, at 698 °K) is higher (12.5%) than

those of Protsenko and Razumovskaya.

Silver Nitrate

[Refer: Table 121, p. 90, for numerical values]

Eight investigations of the specific conductance

for molten AgNCU have been reported [5, 60, 78,

135, 181, 194, 219, 224]. The tabulated values were

calculated from the data of Spooner and Wetmore

[60] (483.2 to 603.2 °K, 13 points). Using the quadratic equation for specific conductance the precision

is 5=1.11 • 10 -3 (0.12%). Compared to the data of

Spooner and Wetmore the results of other investigators show the following maximum departures:

Goodwin and Mailey [5] —1.0 percent (526 °K);

de Nooijer and Ketelaar [226], — 1.0 percent (523 °K);

Polyakov [78], — 1.7 percent (513 °K); Bizouard [181],

0.2 percent (573 °K); Duke and Fleming [135], — 1.6

percent (598 °K); the results of Sundheim and Berlin

[219], and Cowen and Axon [194] show larger departures. The uncertainty of the specific conductance

values is estimated to be about 1 percent.

The exponential equation expresses the tabulated

values of equivalent conductance with a precision

5 = 0.178 (0.45%).

Of the five density studies [25, 36, 54, 60, 224] the

data of Jaeger [25] were selected to calculate the

tabulated values. Compared to the density data of

Jaeger [25] the results of Klemm [36], Spooner and

Wetmore [60], Boardman et al. [54] and de Nooijer

and Ketelaar [224] show maximum departures of — 0.1 percent (600 °K), — 0.4 percent (500 °K), — 0.4

percent (600 °K), and 1.5 percent (548 °K) respectively. The uncertainty of the density values is judged to be about 0.3 percent.

Five investigations of the viscosity have been re- ported [5, 65, 69, 219, 228]. The tabulated values were calculated from the data of Pugsley and Wetmore [69] (530.0 to 593.4 °K, 13 points, Ostwald

viscometer). The cubic equation for viscosity ex- presses the data with a precision 5 = 0.0054 (0.18%).

The uncertainty of the viscosity data is estimated

to be about 1.0 percent.

The investigator, reference, experimental method,

and the maximum percent departure from the values

of Pugsley and Wetmore are as follows: Goodwin

Thallium (I) Nitrate

[Refer: Table 122, p. 91, for numerical values]

Seven investigations of the specific conductance

for molten TINO3 have been reported [110, 125c,

191, 215, 216, 217, 219, 224]. The tabulated values were calculated from the data of Janz and Timidei

[191] (485.5 to 554.5 °K, 17 points). Using the linear

equation for specific conductance the precision is 5 = 9.59- 10 -4 (0.212%). Compared to the data of

Janz and Timidei [191] the results of other investigators show the following maximum departures:

Frame, Rhodes and Ubbelohde [110, 125c], 1.0 percent (524.4 °K); Sundheim and Berlin [219], 0.7 percent (491.9 °K); Bergman and Chagin [215], 5.9

percent (498 °K); and Bokhovkin [216], —4.6 percent (523 °K, 548 °K). Brillant [217] claims agreement

with Ubbelohde but the results are insufficiently

reported for a critical evaluation. The uncertainty

of the specific conductance values is estimated to be about 0.7 percent.

The exponential equation expresses the tabulated

values of equivalent conductance with a precision

5 = 0.0843(0.35%).

Of the two density studies [25, 191], the data of

Janz [191] were selected to calculate the tabulated

values. The maximum departure between the densities reported by Jaeger [25] and Janz [191] is 0.18

percent (552.6 °K). The estimated uncertainty of the

density values is about 0.15 percent.

Four investigations of the viscosity have been re- ported [110, 191, 219, 228]. The tabulated values were calculated from the data of Janz and Timidei

[191] (492.5 to 553.7 °K, 16 points, modified Martin

vsicometer). The cubic equation expresses the data

of Janz and Timidei with a precision 5 = 0.00876

(0.31%). The uncertainty of the data is judged to be

about 1.0 percent.

The investigator, reference, experimental method

and the maximum percent deviation from the values

of Janz and Timidei are as follows: Frame, Rhodes,

and Ubbelohde [110], Ubbelohde viscometer, 5.3

percent; Sundheim and Berlin [219], Ostwald vis- cometer, 7.1 percent: and Protsenko and Razumovskaya [228], vertical capillary viscometer,

+ 12.0 percent.

Vanadium Pentoxide and Chromium Trioxide

[Refer: Tables 123 to 124, p. 91, for numerical

values]

The tabulated values of specific conductance for

molten V2O5 and Cr03 were calculated from the

data of van Arkel, Flood and Bright [68]. The number

of data points, the temperature range, the precision

and the best equation are as follows:

V2 05 - 8 points, 1 140-1237 °K,

5 = 0.00575(2.87%), linear equation.

Cr03 — 7 points, 491-535 °K,

5 = 3.31 • 10 -7 (0.007%), quadratic equation.

Molybdenum Trioxide

[Refer: Table 125, p. 91, for numerical values]

Two investigations of the specific conductance for

molten Mo03 have been reported [68, 76]. The tabulated values were calculated from the data of Morris

et al. [76] (1096 to 1187 °K, 5 points). The exponential

equation for specific conductance expresses the

data of Morris with a precision 5 = 0.00208 (0.22%).

The maximum departure between the specific con- ductance values of Morris [76] and van Arkel [68]

is 58 percent (1168 °K). The uncertainty of the

specific conductance values is estimated to be about

60 percent.

Wiistite (Feo.asO)

[Refer: Table 126, p. 92, for numerical values]

The tabulated values of specific conductance for

molten FeO were calculated from the data of Inouye,

Tomlinson and Chipman [159] (1648 to 1773 °K).

To cover the entire range it became necessary to generate two equations; the number of data points,

the temperature range, the precision appropriate

to this sub-division are as follows:

quadratic equation; 5 points, 1648-1713 °K,

5=16.1 (6.0%)

linear equation; 5 points, 1713-1773 °K,

5=1.18 (0.37%)

Liquid wiistite is a nonstoichiometric melt since an

increase in temperature above the melting point

results in an increase in the Fe/O ratio although the

latter remains less than unity. Chipman [159] has

estimated an overall error of less than 8 percent for

his results. No estimate of the accuracy was

attempted owing to the limited information.

Boron Oxide

[Refer: Table 127, p. 92, for numerical values]

Two investigations of the density for molten B2 03 have been reported [144, 201]. The density data of

the viscosity values in the range 1430 to 1750 °K

with a precision s — 7.61 • 105 (41.6%) and the uncertainty of the data is considered to be about 50 percent, while the exponential equation from the data

of Riebling expresses the viscosities in the range

specific conductance values has not been estimated

due to unreliability of the data. Since the measure31
merits were carried out in an atmosphere of air, the

decomposition of sulfides may have resulted in the

formation of metal molten sulfide solutions; a small

increase in the metal content of many sulfide melts,

in which electronic as well as ionic conduction is known to occur, causes a large increase in the electrical conductance.

Potassium Dichromate

[Refer: Table 169, p. 106, for numerical values]

Two investigations of the specific conductance

for molten K^C^Cb have been reported [8, 110].

between the values reported by Lorenz and Kalmus

[8] and Ubbelohde [110] is 15.5 percent (780 °K).

The uncertainty of the specific conductance values

is estimated to be about 8.0 percent.

is 5 = 9.89 • 10~ 3 (12%). The recent work of Johnson

and Cairns [213] indicates a need for additional

studies since the specific conductivities are higher

36
than those of Moers [165]. An estimate of accuracy was not attempted owing to the limited information

of this private communication [213].

other conductance measurements are available

for comparison a critical estimate of the accuracy

is not possible; however, judging the experimental

techniques of Campbell and Williams, these results can be considered reliable.

values of equivalent conductance with a precision

used to calculate the tabulated values; no estimate

of accuracy was attempted owing to the limited

7. Cumulative Tables of Temperature Dependent Equations

The best temperature dependent equations for

specific conductance, density, equivalent conduct- ance and viscosity (tables 1—174) are summarized

in tables 175-178 respectively. Tables 179-182

contain sets of exponential and power series

equations for specific conductance and viscosity.

The precisions marked with asterisks (*) in table

179 are approximate; the values in these instances

may be 2 to 5 times larger than the table entries. The

uncertainties in brackets, being based on minimal

information, are more qualitative than the un- bracketed values.

NATIONAL BUREAU OF STANDARDS

The National Bureau of Standards1 was established by an act of Congress March 3,

1901. Today, in addition to serving as the Nation’s central measurement laboratory,

the Bureau is a principal focal point in the Federal Government for assuring maximum application of the physical and engineering sciences to the advancement of technology in industry and commerce. To this end the Bureau conducts research and

provides central national services in three broad program areas and provides central national services in a fourth. These are: (1) basic measurements and standards,

(2) materials measurements and standards, (3) technological measurements and

standards, and (4) transfer of technology.

The Bureau comprises the Institute for Basic Standards, the Institute for Materials

Research, the Institute for Applied Technology, and the Center for Radiation Research.

THE INSTITUTE FOR BASIC STANDARDS provides the central basis within the

United States of a complete and consistent system of physical measurement, coor- dinates that system with the measurement systems of other nations, and furnishes

essential services leading to accurate and uniform physical measurements throughout

the Nation’s scientific community, industry, and commerce. The Institute consists

of an Office of Standard Reference Data and a group of divisions organized by the

following areas of science and engineering

Applied Mathematics—Electricity—Metrology—Mechanics—Heat—Atomic Physics—Cryogenics2—Radio Physics2—Radio Engineering2—Astrophysics2—Time

and Frequency.2 THE INSTITUTE FOR MATERIALS RESEARCH conducts materials research leading to methods, standards of measurement, and data needed by industry, commerce,

educational institutions, and government. The Institute also provides advisory and

research services to other government agencies. The Institute consists of an Office of

Standard Reference Materials and a group of divisions organized by the following areas of materials research:

Analytical Chemistry—Polymers—Metallurgy — Inorganic Materials — Physical

Chemistry.

THE INSTITUTE FOR APPLIED TECHNOLOGY provides for the creation of appropriate opportunities for the use and application of technology within the Federal Government and within the civilian sector of American industry. The primary functions

of the Institute may be broadly classified as programs relating to technological measurements and standards and techniques for the transfer of technology. The Institute

consists of a Clearinghouse for Scientific and Technical Information,3 a Center for

Computer Sciences and Technology, and a group of technical divisions and offices

organized by the following fields of technology:

Building Research—Electronic Instrumentation — Technical Analysis — Product

Evaluation—Invention and Innovation— Weights and Measures — Engineering

Standards—Vehicle Systems Research.

THE CENTER FOR RADIATION RESEARCH engages in research, measurement,

and application of radiation to the solution of Bureau mission problems and the

problems of other agencies and institutions. The Center for Radiation Research consists of the following divisions:

Reactor Radiation—Linac Radiation—Applied Radiation—Nuclear Radiation.

1 Headquarters and Laboratories at Gaithersburg, Maryland, unless otherwise noted; mailing address Washington, D. C. 20234.
