Thermochemical Properties of Binary Ba–In Alloys

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 o...

Summary: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 mixing entropies of the alloys and to construct the liquidus curve in the phase diagram. These parameters agree with the literature data.
