Abstract
Phase diagrams for the systems AgCl-CoCl2 and AgBr-CoBr2 were determined by differential scanning calorimetry. The systems are of the eutectic type. Eutectic points are at 271±2 K, 19.5 mol% CoCl2 and 653±2 K, 17.0 mol% CoBr2, respectively. The solid solubility does not exceed 2 and 4 mol% in the systems AgCl-CoCl2 and AgBr-CoBr2, respectively. Thermodynamic activities of components in molten mixtures and molar free enthalpies of mixing were determined for both systems on the basis of liquidus curves. Deviations from ideality were not found to be considerable.
