A thermodynamic study of the equilibrium phase assemblage AgBi ₃S ₅-Bi ₂S ₃-S was made by an EMF-technique, using the RbAg ₄I ₅ solid electrolyte. The ternary phase was synthesized from the pure Ag ₂S and Bi ₂S ₃ in an evacuated silica ampoule and grinded into powder and mixed with appropriate compositions of Bi ₂S ₃ and S, in a series of experiments, for pressing in to pellets. The pellets were assembled to form the galvanic cells Pt (-) | Ag | RbAg ₄I ₅ | AgBi ₃S ₅+ Bi ₂S ₃ + S + (C) | Pt (+). The EMF-measurements were made in the temperature range 299-460 K. In this paper, thermodynamic functions of the ternary phase AgBi ₃S ₅ (pavonite) have been determined. The agreement between the obtained results and the literature values were established.
