Phase diagram study of CaBr2–CaHBr system

A study of binary, CaBr 2 –CaHBr system was carried out by differential thermal analysis (DTA), covering the composition range from 100 % CaBr 2 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...

Zusammenfassung:	A study of binary, CaBr 2 –CaHBr system was carried out by differential thermal analysis (DTA), covering the composition range from 100 % CaBr 2 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 CaBr 2 –CaHBr system is constructed. The system shows an eutectic reaction at 576 °C and the eutectic composition is 79.6 mol% CaBr 2 . Co-existing phases in different phase fields are characterized by X-ray diffraction analysis.
