Phase diagram study of CaBr2–CaHBr system
A study of binary, CaBr2–CaHBr system was carried out by differential thermal analysis (DTA), covering the composition range from 100 % CaBr2 to 100 % CaHBr between room temperature and 800 °C. From DTA results, the contour of solidus and liquidus temperatures with composition is plotted and the phase diagram of CaBr2–CaHBr system is constructed. The system shows an eutectic reaction at 576 °C and the eutectic composition is 79.6 mol% CaBr2. Co-existing phases in different phase fields are characterized by X-ray diffraction analysis.
