Abstract:

The research was concerned with the measurement and interpretation of thermodynamic properties of certain compounds and solid solutions. The following measurements were made. Heat of formation Sb2Se3, Sb2Te3, Bi2Se3, Bi2Te3, Mg2Ge, Mg2Sn, Mg2Pb, In2Te, InTe, In2Te3, In2Te5 solid solutions in the systems Bi2Te3Bi2Se3, Sb2Te3-Bi2Te3, and Sb-Bi. Energies of orderdisorder certain compositions in the systems Bi2Te3Bi2Se3 and Sb2Te3-Bi2Te3. Heats of solution Mg, Ge and Pb in Sn Sb, Se, and Te in Bi. Heats of fusion and melting points Sb2Te3, Bi2Te3, Mg2Sn, Mg2Pb, InTe, In2Te3. Heat capacities near the melting points Sb2Te3, Bi2Te3. The thermodynamic properties were interpreted in relation to the bonding of the compounds and the solid solutions and to the nature of the relevant phase transitions. Author
