THERMODYNAMIC PROPERTIES OF 

MINERALS AND RELATED SUBSTANCES AT 

298.15 K AND 1 BAR (105 PASCALS) PRESSURE 

AND AT HIGHER TEMPERATURES 

By RICHARD A. RoBIE, BRUCE S. HEMINGWAY, and jAMES R. FISHER 

ABSTRACT 

Selected values for the entropy (S0), molar volume (V0), and for the enthalpy and Gibbs 

free energy of formation (~H·, and ~G·r) are given for the elements, 133 oxides~ and 212 

other minerals and related substances at 298.15 K. For those materials for which hightemperature heat-capacity or heat-content data are also available (H.j. - Hi98)/T, S;., (G.j. -

H;98)/T, c~. ~H·r.T. ~G·r.T and log Kr.T are tabulated at 100 K intervals for temperatures up to 

1,800 K. For substances that have solid-state phase changes or whose melting or boili~g 

point is less than 1,800 K, we have also tabulated the properties listed above at the 

temperature of the phase change so that the enthalpy or entropy changes associated with 

the transformation form an integral part of the high-temperature tables. 

INTRODUCTION 

The purpose of these tables of thermodynamic properties is to present 

a critical summary of the available thermodynamic data for minerals and 

related substances in a convenient form for the use of earth scientists. To 

make the tables as useful as possible, we have tried (1) to include enough 

auxiliary data so that a single set of tables would suffice for most calculations, (2) to insure internal consistency, and (3) to provide the means for 

rapid revision and expansion as new data become available. 

This compilation is divided into two sections. In the first section, we 

give values for the entropy (8;98), molar volume (v;98), the enthalpy of 

formation (.~H r, 298 ) and Gibbs free energy of formation (aG0

r, 298), and the 

logarithm of the equilibrium constant of formation (log K1,298) for the 

reference elements, minerals, several oxides, and other substances of 

geological interest, where the subscript 298 implies 298.15 K. The tables 

in the second section contain values for the thermodynamic properties at 

100 K intervals for temperatures up to 1,800 K. The data are arranged in 

order of their conventional mineralogical groups. Within each group (for 

example, the oxides), the listing is by alphabetical order of the chemical 

symbol of the principal cation. 

The data have been taken from recent critical evaluations or have been 

evaluated by the present authors, and uncertainties have been assigned 

to the 298.15 K properties. The sources of data are indicated numerically 
2 THERMODYNAMIC PROPERTIES OF MINERALS 

in the tables and listed in complete form following the tables. These tables 

entirely supersede those of an earlier report on the same subject matter 

by Robie and Waldbaum (1968). 

The true differential heat c'apacity, CJ,, is rarely measured at temperatures above 400 K because of the ease with which the heat content, H~ -

H;98 , may be determined. From the heat-content measurements, one 

may derive approximate values for c;, at high temperatures by differentiation of the H~ - H;98 versus temperature curve. Because many 

users find it more convenient to use analytical expressions for heat 

capacities rather than tabulated values, we have also provided equations 

for the heat capacities at high temperatures. 

In order to derive values of CJ, from the experimental heat-content 

measurements, the measured values of H~ - H;98 were fitted to polynomials having six or fewer terms, and constrained so that at. 298.15 K, 

H~ - H;98 was identically equal to 0 and that the first derivative of the 

fitted equation at 298.15 K had to equal the value of the heat capacity 

obtained by low-temperature calorimetry. This procedure forces the 

values of CJ, derived from the heat-content measurements to join 

smoothly with the more accurate directly measured values of CJ, determined by low-temperature calorimetry. 

The least-squares fitting was done by computer, using either the 

program HINC written by D. W. Osborne of Argonne National Laboratory (D. W. Osborne, written com., 1975) or PHAS20 (Haas and Fisher, 

1976). The equation used to fit the heat-content data was that suggested 

by Haas and Fisher (1976). 

H~ - H;98 = A + BT + CT2 + D/T + ETI~ + FT3 

The first four terms of this equation are those used by Kelley (1960). For 

most phases, only four or five terms have been used. In fitting the data, 

we have followed a general rule that the number of experimental points 

should be approximately three times the number of constants used in the 

equation. The tabulated values of the heat capacity, CJ,, at temperatures 

above 400 K were obtained by differentiation of the heat-content equation. The derived CJ, equation, and its range of validity, is listed at the 

bottom of each high-temperature table. 

Thermodynamic properties of gases at high pressures have not been 

included in these tables. High pressure-high temperature functions of the 

most geologically important gases, H20 and C02 , have been given by 

Bain (1964), Hilsenrath and others (1955), Robie (1966), and Burnham 

and others (1969).

stated temperature. The standard states for the condensed elements are 

the most stable form at 1 bar pressure and the stated temperature. For 

gaseous elements, the standard state is the ideal gas at 1 bar pressure. 

The reference pressure for the standard state adopted for these tables is 

the bar, that is, 10:; pascals. The reasons for this choice are: 

a. In most modern high-pressure-high-temperature equilibrium 

studies on minerals, the pressure is measured in bars. 

b. The use of the bar as the standard pressure in conjunction with the 

joule for energy (or work) simplifies conversion of the Pv term 

(cm3 • bar) in high-pressure calculations of mineral equilibria. Thus, 

1 joule= 10.0 cm3 • bar in contrast with 1 calorie= 41.2929 cm3 • atm 

in terms of older (non-81) units. 

c. The standard atmosphere used as the reference pressure for most 

thermochemical measurements, with the frequent exception of the 

PvT properties of gases, is an arbitrarily adopted unit. In terms of 

the 8I base unit of pressure, the standard atmosphere is equal to 

101325 pascals. 

d. The effect of the change of reference pressure from 1 atmosphere, as 

used in an earlier edition of these tables (Robie and Waldbaum, 

1968), to the present choice of 1 bar has an insignificant effect upon 

the tabulated values of the thermodynamic functions for the condensed phases and only a minor and constant effect for the gas 

phases. 

All data listed in these tables have been corrected to the standard state 

P= 1 bar. For a condensed phase (liquid or solid), it can be readily shown 

that the effect of changing the reference state from 1 atmosphere to 1 bar 

has only a trivial effect upon all the thermodynamic properties tabulated 

in this report except for ~Gor· 

For a gaseous phase, the reference state is the ideal gas, that is, one 

that obeys the equation of state Pv= RT. From the equation of state, it 

follows that: 

v=RTIP 

from which 

(OvlaT)p= RIP, and (02vlaT2)p= o, 

Then from standard thermodynamic rAlations 

(OCplaPh=T(02vlaT2)p=0 

and 

(08/aPh= -(avlaT)p=- RIP

6 THERMODYNAMIC PROPERTIES OF MINERALS 

Also, for an ideal gas, 

dH=TdS+vdP=T(- R/P) dP+(RT/P)dP=O. 

Thus, for a gaseous phase, C~, (H~- H;911 )/T, and .:lHor are independent of 

pressure, but the numerical values of s: .:lGor, and (G~- H;98)/T depend 

upon the choice of pressure. Similarly it can be shown that the change of 

the standard state from a pressure of 1 atmosphere to 1 bar does not affect 

the enthalpy of formation (from the elements in their reference states) 

but will cause a change in the Gibbs free energy of formation of a 

condensed phase if and only if one of the reference elements (usually 

oxygen) is a gas. 

The entropies of the gaseous elements and compounds were converted 

to the standard state P= 1 bar, using the above relations, before entering 

the various thermodynamic data into the data bank. Inasmuch as the 

computer program calculates .:lG0

r.T from .:lHor and the entropies or Gibbs 

energy functions of the constituent elements, the values of .:lG0

r,T are 

automatically corrected to the 1 bar standard state. 

The National Bureau of Standards Technical Note 270 series, the 

JANAF thermochemical tables, and the CODATA tables have retained 

the use of the standard atmosphere as the reference pressure. The 

authors hope that in the near future the General Conference of Weights 

and Measures of the International Bureau of Weights and Measures will 

recommend the elimination of the standard atmosphere as the reference 

pressure. 

Data are listed for the elements in their standard reference states, and 

for a few in nonstandard states; for example, S2 gas and the diamond form 

of carbon. Melting and boiling points and their associated enthalpy 

changes are listed at the bottom of each table of high-temperature properties. A horizontal dashed line in the tables indicates a transition in the 

phase. A dashed line in the columns .:lHor, .:lG0

r, and log Kr, indicates a 

transition in one of the reference elements. Transitions in the reference 

elements are also listed separately at the bottom of each table. Inasmuch 

as most of the high-temperature "heat-capacity" d_ata are actually heatcontent measurements and not true heat capacities (C~), we have followed the practice of Kelley (1960) and have treated all the high-temperature transitions as first order at a single temperature. At the transition 

temperature, the functions (H~- H;911 )/T, S~, and .:lHor:r make a s~epwise 

change; .:lG0r,T and (G~ - H;911)/T, are continuous, but their temperature 

derivatives change abruptly. For those elements (and their compounds) 

for which we have, of necessity, adopted a nonequilibrium phase as the 

reference state (for example, S2 gas above 716.9 K), ther" will also be a 

discontinuity in both .:lGor.T and (G~- - H; 9H)/T at the transition temperature. These properties of the functions must be borne in mind when 

interpolating in the tables. 
REFERENCE STATES AND TRANSITIONS 7 

The reference state adopted for an element above its normal boiling or 

sublimation temperature is not necessarily its equilibrium state. Thus, at 

equilibrium, liquid sulfur boils at 1 bar pressure and approximately 716.9 

K to a gas composed of S, 82, 84 , 86 , SH, etc., but for our reference table, 

we have assumed the gas phase to be only 82. In these ambiguous cases, 

we have chosen either the dominant species in the gas or that species for 

which the best thermodynamic data are available as the reference state. 

Enthalpies and Gibbs free energies of formation for multiple-oxide 

phases using the binary oxides as reference states have also been computed and tabulated, inasmuch as many mineralogical equilibria involve 

only binary or multiple-oxide phases; for example: 

2CaSi03 + CaAl2Si20H = Ca3Al2Si3012 + Si02 

wollastonite anorthite grossular quartz 

and because the enthalpies of formation of most multiple-oxide phases are 

determined using the binary oxides as the reactants. Tables of the thermodynamic functions for temperatures above 298.15 K for multiple-oxide 

phases calculated using the binary oxides as the reference phases immediately follow the appropriate table calculated from the elements 

and are differentiated by the heading "FORMATION FROM THE 

OXIDES" above the columns for ~Hor, ~Gor, and log Kr and by asterisks 

immediately to the right of the entries for ~Hor and ~Gor· 

When using the binary oxides as the reference states, one must remember that in this convention, ~H~ and ~G~ for these reference oxides 

are zero at all temperatures. For example, ~G~ooo for the reaction 

2 wollastonite + anorthite = grossu,lar + quartz 

may be calculated from either the tabulated values of ~G r, 1000 (elements 

as reference states), or ~G~ooo (oxides as reference states) for each of the 

phases in the above reaction. Thus: 

~G~ooo (oxides)={[ -304.53+0]-[ -136.25+2( -91.18)]}= 14.08 kJ 

or 

~G~ooo (elements)={[ -5448. 79+( -729.98)]-[ -3488.51 +2( -1352.17)]} 

=14.08 kJ 

Both calculations must obviously give the same result within the rounding error. However, in estimating the uncertainty in the resulting value 

of ~G~ for a reaction involving onty oxide phases, one should use the 

uncertainties associated with the ~G~ values calculated from the oxides, 

inasmuch as this value usually corresponds more closely to the actual 

calori:Dletric reaction scheme from which the individual ~G~ values were 

obtained. 

The user is cautioned ~ot to mix values of ~G~ calculated from the 

elements for one phase with those obtained from the oxides for another in 

calculating ~G~ of a reaction involving the two phases, because a mean-
8 THERMODYNAMIC PROPERTIES OF MINE~ALS 

ingless result ensues. If a reaction involves both multiple-oxide phases 

and nonoxide phases, as in 

CaF 2 + 2H20 = Ca(OH)2 + 2HF 

fluorite steam portlandite 

AG~ for the reaction must be calculated using only values from the 

tabulated values of AG0

r,T calculated from the elements. 

SOURCES OF DATA 

Many critical evaluations of thermochemical data have been particularly helpful in constructing these tables. For the thermodynamic functions of the elements at high temperatures, we have adopted the values 

selected by Hultgren and others (1973). The CODATA (1976) key values 

have been adopted when they differed significantly from those of 

Hultgren and others (1973). For the sulfides, arsenides, tellurides, 

selenides, and sulfosalts, the summaries by Mills (1974) and by Barton 

and Skinner (1977) have been very helpful. The tabulations by Kelley 

(1960) and by Kelley and King (1961) were particularly useful as a source 

of the pre-1960 heat-content and heat-capacity data. We have also relied 

heavily upon the critical evaluations of the National Bureau of Standards 

Technical Note 270 series (Wagman and others, 1968, 1969, 1971; Parker 

and others, 1971; Schumm and others, 1973) and of the JANAF thermochemical tables (Stull and Prophet, 1971; Chase and others, 1974, 

1975). 

In evaluating the data for the silicates, we have accepted the revised 

values for AHor for those silicates given by Hemingway and Robie (1977), 

which include corrections for the effect of the particle size of quartz and 

for the incorrect value of AHor of gibbsite (Al(OH)a) used in earlier HF 

solution calorimetry studies. For those aluminum silicates for which 

definitive structural evidence of Al!Si disorder was available we have 

corrected the s;98 values for the configurational terms, that is, s~ ~ 0, 

arising from frozen-in Al!Si disorder at 0 K, using the summary of Ulbrich 

and Waldbaum (1976) as a guide. We have also added a correction to the 

entropy of several manganese and iron compounds for which the accepted 

value of S;98 was based upon measurements of the heat capacity only 

above 50 K and for which other evidence indicated the existence of an 

unextracted magnetic contribution to S;98 below 50 K (see, for example, 

Robie, 1965, or Ulbrich and Waldbaum, 1976). 

Values for the thermodynamic properties at 298.15 K for the more 

common aqueous ions are also listed in order to facilitate calculations of 

aqueous equilibria. The reference state for the free energies of the 

aqueous ions is the hypothetical ideal solution ofunit molality. Values for 

AGor are listed on the basis of the usual convention that AG0r, AH0r, So, and 

C~ are identically 0 for aqueous H+ ion in the hypothetical 1 molal ideal 

solution. A more complete discussion of the conventions adopted for 
METHODS OF CALCULATION 

tabulating the thermodynamic properties of aqueous ions has been given 

by F. D. Rossini (1950, Chemical thermodynamics: New York, John 

Wiley, p. 320-370). 

The molar volumes of the condensed phases are principally from the 

summary by Robie and others (1967), augmented by more recent precise 

X-ray measurements of unit-cell parameters. Although our principal 

sources of data for ~Hor, or aG0

r, have been solution or combustion 

calorimetry, for many compoupds the best available data are values of 

aGor, calculated from solubilities, electrochemical cells, reduction equilibria, or decomposition pressure data; we have used these equilibrium 

studies to supplement the calorimetric data whenever possible. For the 

simpler gases, the thermodynamic constants calculated from spectroscopic data are usually the most precise. 

In order to insure internal consistency in these tables and because of 

the complex nature of many of the reaction schemes used to obtain aH0

r, 

or aG0r, we have corrected all the older data to the values adopted here. 

For multiple-oxide compounds, the heats of formation are most commonly measured utilizing the binary oxides as reference phases. However, stoichiometric K20 cannot be prepared reproducibly, and FeO is 

thermodynamically unstable. Furthermore, a-Al20:h corundum, is insoluble in all common aqueous calorimetric solvents. Consequently, mixed 

sets of reactants such as the alkali halides, aluminum hydroxide 

(gibbsite), or an element have frequently been used as the reference 

phases in HF solution calorimetry for determining ~Hor of aluminosilicates. For example, Barany (1964) measured the enthalpy change for 

the reaction 

3Si02+3Al(0Hh+ KC1+9. 731H20= KA12[A1Si30w](0H)2 

+ HC1•12. 731H20 

and by utilizing literature data for the enthalpies of formation of the other 

phases, he calculated aH0

r,298 for muscovite. Accordingly, any improvement of aHor of quartz, gibbsite, sylvite, or aqueous HCl would alter the 

enthalpy of formation of muscovite. Recent measurements of ~H r, 298 of 

gibbsite by Hemingway and Robie (1977) have shown that the value of 

aH0r,298 of gibbsite used by Barany (1964) to calculate the enthalpy of 

formation of muscovite was in error by 11230 J • mol-•, and accordingly we 

have corrected Barany's (1964) calorimetric value for aH0

r,298 of muscovite, and also several other aluminosilicates for which gibbsite was one of 

the reactants, to accord with this new aH(.298 of gibbsite. 

METHODS OF CALCULATION 

Having chosen what we believe are the currently "best available" 

values for H.j.- H;98, or C~(T), 8;98, and either aH0r,298 or aG0r,298, we have 

calculated the Gibbs free energy function, and the enthalpy, free energy, 

and the equilibrium constant of formation at 100 K intervals using the 

following relations:

These values together with C~, S~ and (H~ - H;98)/T are tabulated in the 

second section. 

A Fortran IV program was used for the above calculations. The essential feature of the progr3:m is that internally consistent thermodynamic 

functions can be calculated for several hundred compounds in a single run 

of the computer. This consistency is accomplished by first calculating the 

thermodynamic functions for the reference elements and oxides and then 

holding these data in storage for later computations involving substances 

having these elements or oxides as reference phases. As new thermodynamic data become available, only a minimum number of changes in 

the data base are needed to prepare a completely revised set of internally 

consistent tables. 

The input data supplied to the computer are the identifying name of the 

substance, the entropy, the enthalpy, and Gibbs free energy of formation 

at 298.15 K and their uncertainties, and the entropy and enthalpy increments, S~ - 8;98 and H~ - H;98 , at 100 K intervals, together with the 

number of atoms of each element in the chemical formula. Auxiliary data 

such as the melting and boiling points and enthalpies of melting and 

vaporization are also included. The program computes the formula 

weight of the compound on the basis of the atomic weights of the elements 

(1975 scale) and values forST, .dHI.T, AGI,T, log Kr,T, Cp, (HT - H29s)/T, 

and (GT- H298)/T at 100 K intervals up to 1,800 K. 

Although the absolute value of AG0r,T or .dH0r,T of the more complex 

compounds is rarely known more .accurately than ± 1,000 joules, these 

quantities are tabulated to the nearest 10 joules. This procedure is 

justified because the temperature derivatives of aGar, and AHor, 

(d.dGor/dT)p = - asor (5) 

and 

(dAHor/dT)p= AC~ (6) 

are calculated from the heat-content data, which are known independently of the enthalpy or Gibbs free energy of formation. The practice of 

rounding tabulated values of AGor or A Her on the basis of the uncertainty in 

the absolute value does not utilize the full accuracy of the heat-capacity 

information and destroys the necessary internal consistency between 

.dH0r. 29H and the Gibbs free-epergy function (eq. 3). Furthermore, in many 

instances, the differences between AH0r or .dGor for polymorphs are often 

known more accurately from phase-equilibria or calorimetric investigations than are the individual AH0

r or aGor values for a phase, so that

rounding off again tends to obscure small differences of major importance 

in calculations of geological interest. 

The uncertainties assigned to the properties apply only to the values at 

298.15 K and were taken principally from the original sources of experimental data. By convention, the uncertainty interval reported for 

calorimetric measurements is twice the standard deviation of the mean 

(Rossini, 1956, p. 319); that is, 

8 = 2[L(xi- x)2/n(n- 1)]'12 (7) 

where xi is the value for an individual measurement, xis the arithmetic 

mean of all the measurements, and n is the number of observations. 

For substances where AH0r. 298 is the directly measured quantity, the 

free energy was calculated from 

AG0t,z9s = AH0t.29s - 298.15AS0f.298 (8) 

and the uncertainty in the free energy was calculated from 

aG = [(aH) 2 + (298as)2 + L (298nias)2J';. (9) 

where as is the uncertainty in the entropy of the substance, the asi are 

the uncertainties in the entropies of the i reference elements, and the ni 

are the number of moles of each element in the chemical formula of the 

substance. Uncertainties derived in this manner were rounded upward to 

the nearest 10 joules. 

For substances in which aG is less than a", the basic quantities used in 

the calculation were AG0r, 298 and aG derived from electrochemical cell 

measurements, solubilities, or phase-equilibrium data. Hence, AHor.298 is 

a more indirectly derived quantity having a larger uncertainty. For these 

substances, a" was calculated from 

a"= [(aG)2 + (298as)2 + L (298niasYJ'I:! (10) I 

Camera-ready copy of the tables of the thermodynamic properties, and 

of the bibliography, were prepared from the output file (tape) of the 

FORTRAN IV program, using the WYLBUR text editor and the extended print facility at the Computer Center of the National Institutes of 

Health. 

Several of the tables in the second section are incomplete because of the 

lack of adequate data on the enthalpies of formation or entropies at 298.15 

K of these substances. The tables are nonetheless included, so that when 

such data become available, one may readily calculate the remaining 

functions using equations 2, 3, and 4 given above, or use equilibrium data 

and the third-law method to obtain the standard state enthalpy or Gibbs 

free energy change for the reaction (AH~, or AG~), following the procedures illustrated, for example, by Robie (1965).

285. Heat content for corundum was obtained from a least squares fit to 

the data of Ditmars and Douglas (50) , Fredrickson and Chasanov 

( 60) , Furukawa, and others ( 66), Ginning s and Corruccini 

(70), Krupka, and others (152), and Oett..ing ( 182). For coesite 

and stishovite, the heat content vas assumed to be tbe saae as 

that of quartz (JANAF, 247) after the heat of the ~-p transition 

was subtracted. The heat content vas further constrained to fit 

the heat capacity values given by Holm, Kleppa, and Westrum ( 101 ). 

The entropy of tridymite is an average of that given by Anderson, 

c. T., Am. Chem. soc. Jour., v. 58, p. 568 ( 1936), and a value 

calculated from the equilibrium curve in Tuttle, o. P'., and 

England, J. L., Carnegie Inst. washington, Geophys. Lab. Ann. 

Bept. 1952-53, p. 61. The entropies of phlogopite, monticellite, 

and pyrope are estimates. The entropy of rhodonite vas 

corrected for magnetic contribution below 50 K. High 

temperature heat content of tremolite was estimated. The 

enthalpy of formation of andalusite is from Anderson, P.A.M., 

Newton, R.C., and Kleppa, O.J., Am. Jour. Sci., v. 211, p. 285 

( 1977 ). 

The entropy of pyrope is from the work of Kolesnik, Yu. N., Nogteva, 

V. V., and Paukov, I. Ye., 1977, Geokhimiya, p. 533. The high 

temperature heat capacities of Ca-Al pyroxene are estimates. 

286. The enthalpy of formation of molybdenite at 298.15 K is from O'Hare, 

P.A.G., Benn, E., Cheng, F. Yu., and Kuzmycz, G. (1970 Jour. Chern. 

Thermodynamics, p. 797). The enthalpy of formation of pyrophyllite 

at 298.15 K is from Krupka, K.M., Robie, R.A., and Hemingway, B.S. 

(1979 Amer. Mineral., p. 86) and from Hemingway, B.S., Robie, R.A. 

and Kittrick, J.A. (1978 Geochim. Cosmochim. Acta, p. 1533). 

The enthalpy of formation of anorthite is based upon the heat of 

solution of synthetic anorthite from Kracek (reference 148) rather 

than the heat of solution for anorthite reported by Barany 

(reference 9). The sample used by Barany contained 2 per cent by 

weight of impurities. The corrections made by Barany were probably 

in error for the titanium impurity (see reference 122) and for the 

sodium feldspar impurity (see Kracek, F.C. and Neuvonen, K.J., 

1952, Amer. Jour. Sci., Bowen Volume) by -8.4 kJ/mol, indicating 

a greater stability for anorthite than that obtained from the data 

of Kracek and from the recent data of Charlu, T.V., Newten, R.C. 

and Kleppa, O.J. (1978 Geochim. Cosmochim. Acta, p. 367). 

The enthalpy of formation of grossular, Ca-Al pyroxene, and glass 

of anorthite composition are based upon the enthalpy of formation 

choosen for anorthite.
