Quasi Ternary System

Chemical interactions in the system were studied by methods of physicochemical analysis (DTA, XRD, MSA, determination of density and microhardness) and its phase diagram was constructed. It was found that the phase diagram of the system is a non-quasi-binary section of the quasi-ternary system As2Te3-Cr2Te3-CuTe. At room temperature in the system of solid solutions based on Cu3As4Te9 reaches - 5 mol. % CrAsTe3. The region of the solid solution based on the CrAsTe3 compound has not been established in practice. The dependence of the microhardness and density of alloys of the Cu3As4Te9-CrAsTe3 system on the composition has been investigated.

The character of the interaction in the InAs2Se4 -InAs2SSe3 system was investigated and its phase diagram was constructed by DTA, XRD, MSA, as well as by measuring the microhardness and determining the density of the alloys. It was found that the InAs2Se4 -InAs2SSe3 section is a quasi-binary section of the In-As-S-Se quaternary system. Solid solutions based on InAs2Se4 at room temperature reach 10 mol % InAs2SSe3, and on the basis of InAs2SSe3 it extends to 15 mol % InAs2Se4. The lattice parameters are calculated from the region of solid solutions based on InAs2Se4 and InAs2SSe3.

Quasiternary System

The alloys of the As2Te3-Cu2Cr4Te7 system were investigated by methods of physicochemical analyzes (DTA, XRD, MSA, as well as density and microhardness measurements) and its phase diagram was constructed. Studies have shown that the As2Te3-Cu2Cr4Te7 system is a partially quasi-binary section of the As2Te3-Cr2Te3-CuTe quasiternary system. In a system at room temperature based on As2Te3, solid solutions reach 3.5 mol %, and based on the Cu2Cr4Te7 solid solutions reach up to 17 mol %. Eutectic equilibrium and peritectic transformation occur during chemical interactions between As2Te3 and Cu2Cr4Te7 compounds in the system.

Spinel Solid Solutions

Phase relations in two binary systems MgAl2O4–ZnAl2O4 and MgAl2O4–Mg2TiO4 have been studied and phase diagrams for them have been constructed. Based on the data of x-ray phase and crystal-optical analyses, the formation of a continuous series of solid solutions with spinel structure between the terminal members of the systems studied has been established. In the MgAl2O4–ZnAl2O4 system the solid solution is stable in the range from room temperature to melting temperature. In the MgAl2O4–Mg2TiO4 system the solid solution decomposes below 1380 °C, yielding the formation of limited regions of homogeneity on the basis of MgAlM2O4 and Mg2+2δ Ti1–δO4. Decomposition of the solid solution is accompanied by crystallization of MgTiO3.
