MEASUREMENT OF THERMODYNAMIC PROPERTIES OF COMPOUNDS OF ELEMENTS IN GROUPS II, IV V AND VI.

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)
