The results of comparative thermodynamic analysis of AuIn–Sb section in ternary Au–In–Sb system are presented in this paper.
Investigation was carried out experimentally, using Oelsen calorimetry at the temperature 873 K and analytically, applying
different predicting methods––Toop and Muggianu in the temperature interval from 873 K to 1673 K. The values for integral
molar Gibbs excess energies and antimony activities have been determined and compared at temperature of 873 K, which indicated
to good agreement between experimental results and results obtained using Toop predicting model.
