Abstract: A thermo-electric device comprises at least one thermo-electric element of material having the general formula MSy-xSex, where M is at least one of the rare earth elements; y=0,5-1,0; x=0-0,2.  Such elements are n-type and are useful when operating within a temperature range of 425-1,000 DEG C. in a protective atmosphere. Production of thermo-electric elements.  The reactants M, S, and Se (if x > 0) in finely divided particle form are mixed and sealed in a vessel of inert material under a vacuum of at least 4 X 10-4mm. Hg. M should have a purity of at least 99%, preferably 99,6% or higher; S should have a purity of at least 99,5% and Se a purity of at least 99,9%.  The reactants are heated to a temperature within the range 626 DEG  - 800 DEG C. at a rate of 150 DEG  - 250 DEG C./hr. and maintained thereat for 10 to 120 minutes.  When cool, the reaction product is finely divided and compacted at a pressure of 700 - 14,000 Kg./cm.2 at room temperature, the compacted element then being fired in vacuo at 800 DEG  - 1,600 DEG C. for 15 - 60 minutes.  In an example, 150,35 gms. Sm and 24,05 gms. S are mixed and heated at about 250 DEG C./hr. to 800 DEG C., at which temperature the mixture is maintained for about 30 minutes to produce Sm S0,75,. When cool, the Sm S0,75 is ground and charged into a series of tungsten carbide moulds and compacted with a pressure of 7,000 Kg./cm.2 into cylindrical pellets which are fired at temperatures from 800 - 1,300 DEG C. for 30 minutes.  In other examples, the same process is used with modified starting quantities to produce Sm S0,50 and Sm S.  The Sm in these three examples may be replaced by Ce, Pr, Nd, Eu, Gd, Tb, Dy, Ho, Tm, Yb and Lu.  In a further example, 75,17 gms. Sm, 70,07 gms. Ce and 32,06 gms. S produce Sm Ce S by a similar process. In another example, Sm S0,9 Se0,1 is likewise produced from 150,35 gms. Sm, 28,85 gms. S and 7,89 gms. Se. La S0,5 is produced by heating a mixture of 138,92 gms. La and 16,03 gms. S. at a rate of 150 DEG C./hr. to 750 DEG C., and maintaining it thereat for 1 hour; when cool, the compound is compacted into pellets under a pressure of 14,000 Kg./cm.2 and fired at 1,200 DEG C. for 1 hour.  In a final example, 167,27 gms. Er and 32,06 gms. S are heated at 200 DEG C/hr. to 630 DEG  C., kept thereat for 10 minutes, compacted into ErS pellets at 700 Kg./cm.2, and fired at 900 DEG C. for 20 minutes.  The Specification and Fig. 3, (not shown) contain tabulated and graphic data relating to the electrical and thermoelectrical properties of some of the above materials.
