| Abstract Scope |
The phase equilibria of the Ag–Ge–Sb–Te system in the part Ag8GeTe6–Ge–GeTe–Sb2Te3 were investigated by the EMF method. According to the experimental data on the EMF versus temperature of the electrochemical cells, the analytical equations of the Gibbs energy were obtained for the GeSb8Te13, GeSb6Te10, GeSb4Te7, GeSb2Te4, Ge2Sb2Te5, Ge3Sb2Te6, and Ge4Sb2Te7 compounds. The thermodynamic properties of silver-saturated tetradymite-like compounds have been calculated for the first time. |
