Abstract
Phase equilibriums were established in the 3Tl2Se+Sb2Te3↔3Tl2Te+Sb2Se3 mutual system mainly by the X-ray powder diffraction and differential thermal analyses, with the aid of microhardness and EMF measurements applied to equilibrated alloys. According to the obtained experimental results the phase diagrams in form of the polythermal section and isothermal section at 300K as well as the projection of the liquids surface have been constructed. It was found experimentally that the system is mutually reversible and is characterized by a wide solid solubility fields along the TlSbSe2–TlSbTe2 subsystem and within the Tl2Se–Tl9SbSe6–Tl9SbTe6–Tl2Te subsystem. The homogeneity and primary crystallization fields as well as the types and coordinates of non- and monovariant equilibriums were determined. The dependencies of crystallographic parameters, microhardness and EMF values upon the composition are discussed. From the EMF measurements, the partial molar functions of thallium (ΔG¯,ΔH¯,ΔS¯) were calculated for the revealed nonstoichiometric quaternary phases.
