Abstract

The thermochemical properties of binary Ba–In melts were studied using calorimetry at 1070–1320 K over a wide composition range. It is shown that these melts are characterized by significant exothermic heat effects of mixing. The ideal associated solution model was used to calculate the activities of components, Gibbs energies, and entropies of mixing for the alloys and to construct the liquidus curve of the phase diagram. They agree with the literature data.
