Abstract

The dependence of EMF (E) of Ag|AgI|glass Ag2|GeS3|D galvanic cells on temperature is studied in the range of 555–595 K (Ag, D are electrodes of galvanic cells, D are equilibrium three-phase alloys of the Ag-Ge-Te system; AgI|glass Ag2GeS3 is a two-layer membrane with purely ionic (Ag+) conductivity). Analytical equations describing the E,T-dependences are used for calculation of the values of thermodynamic functions of solid solutions of β-Ag2Te, γ-Ag8GeTe6, and α-GeTe phases of the Ag-Ge-Te system in the standard state.
