Thermodynamic calculation of the liquidus in ternary mutual systems
Asif Mamedov, Ismayl Mekhdiev, Zakir Bagirov
Equations have been obtained to calculate the liquidus surface of reversibly mutual systems. The equations have been used for the system zinc, cadmium//arsenic, tellurium with components Cd3As2, CdTe, ZnTe, and Zn3As2. The partial excess molar energy components of the system Zn, Cd//As, Te are determined from the corresponding characteristics of boundary binary systems on the assumption that the contribution of a boundary system to the partial molar free energy of mixing on the isoconcentrate of the cation or anion portions is constant. Good agreement between theory and experimental data was obtained for the liquidus surface.
