The SnTe–Sb2Te3–Te system has been studied in the temperature range 300–430 K using emf measurements on reversible concentration cells of the type (–)SnTe(s) | liquid electrolyte, Sn2+ |(Sn–Sb–Te)(s)(+). The system has been shown to consist of two three-phase regions, separated by the SnSb2Te4–Te tie line. The best fit equation for the temperature-dependent emf data has been used to evaluate the partial thermodynamic functions of the SnTe and Sn in the alloys. Using these data, subsolidus phase diagram data for the SnTe–Sb2Te3–Te system, and relevant thermodynamic functions for SnTe and Sb2Te3, we calculated the standard Gibbs energy of formation, standard enthalpy of formation, and standard entropy of the SnSb2Te4 compound. © 2017, Pleiades Publishing, Ltd.

The phase equilibria in the 2Cu2S + GeSe2 ↔ 2Cu2Se + GeS2 reciprocal system were experimentally investigated by means of differential thermal analysis (DTA) and powder X-ray diffraction (PXRD) technique as well as electromotive force measurements (EMF) of concentration chains with Cu4RbCl3I2 solid electrolyte. Five isopleth sections Cu8GeS6–Cu8GeSe6, Cu8GeSe6-Cu2Se, Cu2GeS3–Cu8GeSe6, Cu2S–GeSe2 and Cu2Se–GeS2 and four isothermal sections at 300, 800, 1100 and 1200 K as well as liquidus surface projection of the system were constructed based on the experimental data. The system was found to be mutually reciprocal with the formation of continuous or wide areas of solid solutions series along the Cu2S–Cu2Se, Cu2GeS3–Cu2GeSе3, Cu8GeS6–Cu8GeSe6 and GeS2–GeSe2 binary systems. The partial molar thermodynamic functions of the copper for the Cu8GeS6-xSex (where x = 0.6; 1.2; 1.8; 2.4; 3.6; 4.8; 5.4 and 5.7) solid solutions were calculated based on the EMF measurements data. © 2016 Elsevier B.V.

Physics of the Solid State | Year: 2017

The effect of composition and temperature on the electrical conductivity and the permittivity of the Tl(GaS2)1 – x(InSe2)x has been studied. It is found that the permittivity and the conductivity increase with temperature and vary linearly as the InSe2 concentration increases: in this case, the conductivity decreases and the permittivity increases. It is confirmed that the system under study contains two series of solid solutions. It is shown that the commensurate–incommensurate phase transition temperatures shift to lower values as the InSe2 concentration increases. © 2017, Pleiades Publishing, Ltd.

Phase equilibria in the Cu2S–Cu3AsS4–S system were studied by differential thermal analysis and X-ray powder diffraction. Important plots characterizing this system were constructed, namely, the T–x diagrams of the lateral quasi-binary systems Cu2S–Cu3AsS4 and Cu3AsS4–S, some internal sections, the isothermal section of the phase diagram at 300 K, and the projection of the liquidus surface. The fields of primary crystallization of phases and the types and coordinates of in- and monovariant equilibria were found. A wide region of separation of liquid phases was detected in the system. © 2017, Pleiades Publishing, Ltd.

Phase equilibria in the Cu–Cu2Se–As were investigated by differential thermal analysis and X-ray powder diffraction analysis. Informative plots describing this system were constructed, viz., the polythermal sections Cu0.667Se0.333–As, Cu0.667Se0.333–Cu0.735As0.265, and Cu0.8Se0.2–As, the isothermal section of the phase diagram at 300 K, and the projection of the liquidus surface. The obtained results differ from the published data in length of fields of primary crystallization of phases and in coordinates of a number of invariant equilibrium points. © 2017, Pleiades Publishing, Ltd.

The Ag2Se–GeSe2–SnSe2 system has been studied in the temperature range 290–430 K using differential thermal analysis, X-ray diffraction, and emf measurements concerning silver concentration cells with Ag4RbI5 as a solid electrolyte. We have constructed a number of vertical sections; the 300-, 800-, and 900-K isothermal sections of the phase diagram; and a projections of the liquidus surface. It has been shown that the only pseudobinary join, Ag8GeSe6–Ag8SnSe6, contains a continuous series of solid solutions between the two crystalline phases of the constituent selenides and divides the system into two independent subsystems. Ag2Se–Ag8GeSe6–Ag8SnSe6 is a univariant, eutectic subsystem, and GeSe2–Ag8GeSe6–Ag8SnSe6–SnSe2 is an invariant eutectic subsystem. Experimental emf data were used to evaluate partial thermodynamic functions of the silver in the high-temperature and low-temperature Ag8Ge1–xSnxSe6 solid solutions. © 2017, Pleiades Publishing, Ltd.

The problem of component distribution in solid solution crystals grown from a melt fed by rods made of the components of the system, with allowance for the dependence of their segregation coefficients on the melt composition, has been solved in the Pfann approximation. Examples determining the conditions for growing homogeneous single crystals of solid solutions with a specified composition and obtaining (in a unified cycle) crystals composed of several uniform parts of different compositions are presented for the Si Ge system. The good prospects of using the method of double feeding the melt for growing single crystals of semiconductor solid solutions with specified graded and/or uniform compositions are shown. © Pleiades Publishing Inc. 2010.
