摘要

The phase equilibriaPhase equilibria of the Ag–Pd–Ge–S system in the phase region Ge–GeS2–PdS2–PdS–Ag2PdS2 were established by advanced electromotive force (EMF) method. For the phase space studies and thermodynamic measurements, the following type of electrochemical cells (ECCs) were assembled: (−) С || Ag || SЕ || R(Ag+) || PЕ || С (+), where C is the graphite; Ag is the powdered silver; SE is the purely ionic Ag+ conductor (Ag2GeS3 glass); PE is the positive electrode; R(Ag+) is the diffusionDiffusion region of the Ag+ ions from SE to PE. The values of the standard thermodynamic functions (Gibbs energyGibbs energy, enthalpy, and entropy) of the Ag2PdGeS4 compound were established for the first time from the linear temperature dependencies of EMF of the ECCs. The thermodynamic data determined in this work will contribute to a better understanding of the studied chalcogenidesChalcogenide compounds and their user limitations.
