Qısa məlumat

The Ag-As-S system has been studied in the composition region Ag 2S-As2S3-S at temperatures from 300 to 380 K using emf measurements with Ag4RbI5 as a Ag+ ion conducting solid electrolyte, and its subsolidus phase diagram has been mapped out, including the ternary compounds AgAsS2, Ag 3AsS3, and Ag7AsS6. From the emf data, we have calculated the partial molar thermodynamic functions ((Δ Ḡ,Δ H̄,Δ S)) of the silver in the three-phase regions AgAsS2 + As2S5 + As2S3, Ag3AsS3 + AgAsS2 + S, and Ag 7AsS6 + Ag3AsS3 + S, which were then used to evaluate the standard thermodynamic functions of formation and standard entropies of the ternary compounds by the method of potential-determining reactions. © 2014 Pleiades Publishing, Ltd.
