| Popis: | The SnTe–Sb2Te3–Te system has been studied in the temperature range 300–430 K using emf measurements on reversible concentration cells of the type (–)SnTe(s) | liquid electrolyte, Sn2+ |(Sn–Sb–Te)(s)(+). The system has been shown to consist of two three-phase regions, separated by the SnSb2Te4–Te tie line. The best fit equation for the temperature-dependent emf data has been used to evaluate the partial thermodynamic functions of the SnTe and Sn in the alloys. Using these data, subsolidus phase diagram data for the SnTe–Sb2Te3–Te system, and relevant thermodynamic functions for SnTe and Sb2Te3, we calculated the standard Gibbs energy of formation, standard enthalpy of formation, and standard entropy of the SnSb2Te4 compound. |
