Abstract

In this study, thermodynamic properties of AgSbS₂ and Ag₃SbS₃ have been determined by the advanced EMF method. All the measured phases have been carefully synthetized in evacuated quartz glass ampoules. The synthesized phases were analyzed by the SEM-EDS and DSC techniques. Solid state electrochemical cells of the type (Ag|AgI|Ag-Sb-S-compounds in equilibrium) were applied in EMF measurements. Independent experimental apparatuses were applied to prove the reproducibility of the measured EMF values. The measured E vs. T relations were analyzed, and thermodynamic functions of AgSbS₂ and Ag₃SbS₃ have been determined. Accurate thermodynamic properties of both phases including data in new temperature ranges have been obtained. The results were compared with the available literature data and discussed.
