PHASE EQUILIBRIA IN THE Ag8GeS6–Ag8GeSe6 SYSTEM AND SOME PROPERTIES OF SOLID SOLUTIONS

S.M.Bagheri, I.J.Alverdiyev, M.B.Babanly

The Ag₈GeS₆–Ag₈GeSe₆ system has been studied by using DTA and XRD methods and EMF measurements with the Ag₄RbJ₅ solid electrolyte. The T–x phase diagram and corresponding ²composition–property² diagrams were constructed. It is established that the system is characterized by continuous solubility fields in the liquid state and also between high temperature cubic modifications of starting compounds. The formation of high temperature solid solutions decreases the temperature of polymorphic transitions of both components.

Keywords : Ag8GeS6–Ag8GeSe6 system, chalcogenides of silver–germanium, phase equilibria, thermodynamic functions, solid solutions, polymorphic transformations, thermodynamic functions, EMF method
