Measuring the thermodynamic properties of saturated solid solutions in the Ag2Te-Bi-Bi2Te3 system by the electromotive force method
Abstract
The temperature dependence of the electromotive force (EMF) of Ag|AgI|glass Ag2GeS3|D galvanic elements (where Ag, D are galvanic element electrodes, D is equilibrium three-phase alloys in the Ag2Te-Bi-Bi2Te3 system, AgI|glass Ag2GeS3 is a two-layer membrane with purely ionic (Ag+) conductivity) is studied in the range of 490-550 K. Analytical equations are obtained for the temperature dependences of the Gibbs energies of the formation of saturated solid solutions of the Bi14Te6, Bi2Te, BiTe, and Bi2Te phases from elements in the Ag2Te-Bi-Bi2Te3 system. E( T) analytical equations are used to calculate the standardstate thermodynamic functions of saturated solid solutions of the Bi14Te6, Bi2Te, BiTe, and Bi2Te3 phases in the Ag2Te-Bi-Bi2Te3 system.
