“…Understanding the phase relationships in the respective systems is always useful for developing directed methods for the synthesis of new materials [20][21][22]. Systems characterized by the formation of solid solutions are of particular interest since the material properties can be changed by varying the composition [23][24][25].…”

Phase equilibria in the Ag8GeS6-Ag8GeTe6 and Ag8GeSe6-Ag8GeTe6 systems were studied using differential thermal analysis and powder X-ray diffraction technique. The T-x phase diagrams were constructed. It has been found that both systems are partially quasi-binary and are characterized by the formation of continuous series of substitutional solid solutions between Ag8GeTe6 and high-temperature cubic modifications of Ag8GeS6 and Ag8GeSe6. When solid solutions are formed, the temperatures of polymorphic phase transitions of these compounds decrease. This leads to the stabilization of the ion-conducting cubic phase in the 40 mol% Ag8GeTe6 range of compositions at room temperature and below. The regions of homogeneity based on Ag8GeS6 and Ag8GeSe6 are 15 and 10 mol.%, respectively. The crystal lattice parameters of the identified solid solutions were calculated from the XRD data, and their linear dependence on the composition is shown

The paper presents the results of a study of phase equilibria in the 6Ag2Se+Ag8SiTe6 6Ag2Te+Ag8SiSe6 reciprocal system by DTA and XRD methods. The projection of the liquidus surface, isothermal sections at 300, 500, 1150 K, and some polythermal sections of the phase diagram are constructed. It is shown that the system is reversible-reciprocal. It is characterized by the formation of continuous high-temperature solid solutions along the Ag8SiSe6-Ag8SiTe6 () and Ag2Se-Ag2Te () boundary systems. It has been established that the liquidus surface of the reciprocal system consists of two fields of primary crystallization - and -phases. These surfaces are delimited by a eutectic curve with monovariant equilibrium L+. In the subsolidus part of the system, a complex interaction is observed associated with the polymorphism of the initial compounds and phases based on them
