The phase equilibria in the Cu-Sb-S-I quaternary system were studied by differential thermal analysis and X-ray phase analysis methods in the CuI-SbSI-SbI3 concentration intervals. The boundary quasi-binary section CuI-SbSI, 2 internal polythermal sections of the phase diagram, as well as, the projection of the liquidus surface were constructed. Primary crystallisation areas of phases, types, and coordinates of non- and monovariant equilibria were determined. Limited areas of solid solutions based on the SbSI (b-phase) and high-temperature modifications of the CuI (α1- and α2- phases) were revealed in the system. The formation of the α1 and α2 phases is accompanied by a decrease in the temperatures of the polymorphic transitions of CuI and the establishment of metatectic (3750C) and eutectoid (2800C) reactions. It was also shown, that the system is characterised by the presence of a wide immiscibility region that covers a significant part of theliquidus surface of the CuI and SbSI based phases

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.

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.
