“…The heat of formation from the solid components, obtained by adding the heat of fusion of tin, results in the value -14.3 ___ 0.4 kcal/mole for AHsos. This is in satisfactory agreement with the values reported in the literature [7][8][9], obtained by EMF and solutioncalorimetric techniques.…”

“…Calculations from Wagner's analysis yield a value for the free energy of formation, AG[SnO) + Te(1) = SnTe(s), 1078 K], of -7.0 +_ 0.5 kcal/mole. The corresponding value from McAteer and Seltz [8] extrapolated to 1078 K is -10.8 kcal/mole. From the wide disagreement between these two values it may be concluded that the assumption of the regular behaviour of the melt adopted in Wagner's analysis may not be valid for the Sn-Te liquid alloy.…”

“…Hirayama [7] has compiled various thermodynamic properties of SnTe. McAteer and Seltz [8] determined its free energy of formation in the temperature range 533-663 K by an EMF technique, using a LiC1-KCI + SnC12 molten-salt electrolyte. Robinson and Bever [9] have determined the heat of formation in a liquid-metal solution calorimeter, using bismuth as a solvent.…”

The heats of formation and fusion of SnTe were determined in a differential thermal analysis calorimeter. Its free energy of formation was calculated by the analyses due to Wagner and Jordan using this heat of fusion and liquidus data. The experimentally determined value of the heat of formation and the calculated free energy of formation were combined to obtain the entropy of formation. The thermodynamic properties were interpreted in terms of the structure and bonding of the compound.The system Sn-Te, as shown in the phase diagram (Fig. 1) [1, 2], contains only one compound, SnTe. This melts congruently and has a narrow range of homogeneity (50.1-50.9 at. % Te). This compound has gained prominence as a material for generation and detection of infrared radiation [3] and thermoelectric energy conversion [4]. The thermodynamic properties of tin telluride have not been systematically investigated. The available data are limited and show wide disagreement. For example, the published values of its heat of fusion, based on two different techniques, are 7.9 and 10.8 kcal/mole, respectively [5,6]. Hirayama

“…For cadmium, the necessary properties are taken from Hultgren et al [21] and have also been adopted by SGTE. [25] They are: The corresponding quantities for tellurium are taken from our third law analysis [9] of the crystal-liquid-vapor equilibrium. As mentioned earlier, the heat capacity above the melting point is quite different from that given by Mills [7] and used in previous studies.…”

“…There are four line segments below 722.6 K terminated by symbols. [25][26][27][28] The symbols indicate the temperature limits of the measurements. The measurements of Shamsuddin and Nasar [29] are shown as solid triangles between 640 and 845 K. They were extracted by us from a scaled plot of emf versus T. The cell electrodes were described as Cd(l) and CdTe(c) + Te(c,l).…”

The high temperature heat capacity, Gibbs energy of formation, and standard enthalpy and entropy of formation at 298 K are combined with thermodynamic data for Cd and revised data for Te to provide an internally consistent data set for CdTe(c). Equations are given for the Gibbs energy of formation from Cd(g) and Te 2 (g) and from the solid or liquid elements as a function of temperature. These give values similar to those used before. However, the derived enthalpy and entropy of formation are significantly different due to a revised heat capacity for CdTe(c). The standard enthalpy and entropy of formation at 298.15 K from the gases are 2293262 J/mol and 2200.593 J/mol K, respectively. From the solid elements they are 2100270 and 24.5334.
