Thermodynamic Properties of Solid Monoxides, Monosulfides, Monoselenides, and Monotellurides of Ge, Sn, and Pb.

A thermoanalytical investigation of the thermodynamic properties of tin telluride

“…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.…”

“…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 [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.…”

Thermochemistry of (germanium + sulfur) IV. Critical evaluation of the thermodynamic properties of solid and gaseous germanium(II) sulfide GeS and germanium(IV) disulfide GeS2, and digermanium disulfide Ge2S2(g). Enthalpies of dissociation of bonds in GeS(g), GeS2(g), and Ge2S2(g)

“…THERMODYNAMIC PROPERTIES OF GeS (cr,orthorhombic) In the course of their assessments of the thermodynamic properties of GeS(cr), Gurvich et al (12) and Mills (13) used the low-temperature heat capacities C°p ,m from Weller and Kelley's (14) adiabatic calorimetric measurements over the temperature range from 52 K to 296.4 K as the sole experimental basis of the estimated thermodynamic properties at Tq300 K. Wiedemeier et al (15) (17) as a reference for the quantity (D…”

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.…”
