THERMODYNAMIC INVESTIGATION OF Cu8GeS6 COMPOUND BY EMF METHOD WITH SOLID ELECTROLYTE

Z.M.Aliyeva, I.J.Alverdiyev, Y.A.Yusibov, M.B.Babanly

The Cu₈GeS₆ compound has been investigated by EMF measurements of the concentration chain (–) Cu (solid) | Cu₄RbCl₃I₂ (solid) | Cu₈GeS₆ (solid) (+) in 295–390 K temperature interval. It was obtained that pointed compound has a polymorphic transformation at 328 K. The partial and integral thermodynamic functions of both crystalline modifications of Cu₈GeS₆ as well as heat and entropy of its polymorphic transformation are calculated based on EMF measurements.

Keywords : copper-germanium sulfide, Cu8GeS6, termodynamic functions, polimorphic transformation, EMF method
