Аннотация:Using literature data, experimental data obtained in this study, and a unified thermodynamic model, we have calculated the T-x-y phase diagrams of all the pseudoternary systems formed by the Group 14 chalcogenides: (Ge, Sn, Pb)Te, Pb(S, Se, Te), and Sn(S, Se, Te). The phase diagrams have been constructed using the known interaction parameters of the pseudobinary systems and the ternary interaction parameters derived from experimental data. The systems have small negative ternary interaction parameters, which decrease in the order β-(Ge, Sn, Pb)Te < β-Pb(S, Se, Te) < δ-Sn(S, Se, Te).
