Thermodynamic properties of alloys of the binary Gd–In system

Resumo

The thermochemical properties of melts of the binary Gd–In system were studied by the calorimetry method at 1470–1700 K over the whole concentration interval. It was shown that significant negative heat effects of mixing are characteristic features for these melts. Using the ideal associated solution (IAS) model, the activities of components, Gibbs energies and the entropies of mixing in the alloys of this systems and its phase diagram were calculated. They agree with the data from literature.
