Summary:The phase diagram of binary LiBr-Ca[Br.sub.2] system was investigated using differential thermal analysis (DTA) between room temperature and 800°C. From the DTA results obtained over the entire range of composition from pure LiBr to pure Ca[Br.sub.2] in steps of ~5 mol%, the phase diagram was constructed and is reported here. The results indicated the possible existence of a compound at 50 mol% LiBr, namely, LiCa[Br.sub.3]. The compound undergoes peritectic decomposition at 552°C. The system shows a eutectic reaction at 532°C between this compound and LiBr phase, and the eutectic composition is close to 80 mol% LiBr. The compound LiCa[Br.sub.3] decomposes into Ca[Br.sub.2] and LiBr phases below 272°C. Co-existing phases in different phase fields are characterized by X-ray diffraction analysis.
