Thermodynamic properties of the intermediate phases of the Ag-Sb-Se system

The emf (E >) dependence of C|Ag|AgI|glass Ag2GeS3|D|C galvanic elements on temperature is studied in the range of 470 to 575 K (C represents current electrodes, D denotes equilibrium three-phase alloys of individual Ag-Sb-Se systems, and AgI|glass Ag2GeS3 is a bilayer membrane with purely ionic (Ag+) electroconductivity). Analytical equations E > = E >(T) are used to calculate the thermodynamic functions of saturated solid solutions of the AgSbSe2, Sb2Se3, and Ag2Se phases of the Ag-Sb-Se system in the standard state.
