| Popis: | The calculated results of thermodynamic properties in ternary Au-Ga-Sb system by general solution model were presented in this paper. The calculations were carried out in nine cross sections from all three corners in the temperature range of 973–1,573 K, and integral molar excess Gibbs energies, partial molar Gibbs energies, activity coefficients and activities for all components are obtained. The activity of gold and gallium shows negative deviation from Rault’s law for all investigated sections, while antimony activity is close to the line of ideal conditions and even coincides with the line for high content of antimony in the alloy. Data obtained by calculation were compared with those found in literature. It is concluded that compared values show reasonable good agreement. |
