Thermodynamic Descriptions for the Sn-Te and Pb-Sn-Te Systems

“…The relative enthalpies for the SnTe compound, defined with respect to the enthalpy value at 300 K, were calorimetrically determined by Blachnik et al 25 and Medzhidov and Rasulov. 26 The enthalpies of formation of SnTe were calorimetrically measured by Robinson and Bever, 27 Hirayama, 28 and Vecher et al 29 By various techniques such as thermal analysis, the liquidus surface of the Pb-Sn-Te ternary system was extensively characterized by Hatto et al, 30 Muszynski et al, 31 Zlomanov et al, 32 Abrikosov et al, 33 Calawa et al, 34 Hiscocks and West, 35 Wagner and Willardson, 36 Mikhailov et al, 37 Astles et al, 38 Wagner and Woolley, 39 Linden and Kennedy, 40 Cadoz et al, 41 Laugier et al, 42 Shotov and Davarishvili, 43 Petukhov et al, 44 and Szapiro et al 45 With the aid of lattice parameter and other techniques, the homogeneity range for (Pb,Sn)Te was investigated by Zlomanov et al, 32 Calawa et al, 34 Wagner and Woolley, 39 Thompson, 46 Harman, 47 Hewes et al, 48 Dionne and Woolley, 49 and Gaskov et al 50 With a calorimeter, the enthalpies of mixing for the ternary melts were measured by Kattner et al 6 for various composition configurations at 1228 K, where the obtained mixing enthalpies generally show an exothermic behavior.…”

Thermodynamic Properties of Solid Binary Antimonides

“…Metal-solution calorimetry has been used to determine Δ H ° for Sb 2 Te 3 by Howlett et al (bismuth solvent, 623 K) and Vecher et al (tin solvent, 700 K). , Vecher et al provide a value of −60.665 kJ/mol, without providing a temperature; Howlett et al list −56.481 kJ/mol at 273.15 K. EMF techniques have also been used to measure Δ G ° for Sb 2 Te 3 : Gerasimov and Nikol’skaya (molten-salt electrolyte, 653–693 K), , Semenkovich and Melekh (molten-salt electrolyte, 530–560 K), and Mallika and Sreedharan (yttria-stabilized zirconia, 588–722 K) . Boncheva-Mladenova et al measured the partial pressures of Sb 4 and Te 2 generated by decomposition (697–819 K) .…”

Solid‐State Electrochemical Study of In‐Sb Liquid Alloys

“…3 and are combined togive hG "~, which is plotted as a function of composition in Fig. 4 is the experimental enthalpy of mixing as measured by several investigators (23)(24)(25)(26). Also summarized in Fig.…”

“…Also shown in Table I is a summary of the enthalpy of fusion of InSb, AHf" [InSb]. The mixing of pure In and pure Sb produces a negative enthalpy change as determined calorimetrically by several investigators (15,(23)(24)(25)(26)(27)(28). The mixing of pure In and pure Sb produces a negative enthalpy change as determined calorimetrically by several investigators (15,(23)(24)(25)(26)(27)(28).…”
