Abstract:The phase diagram of binary system EuCl3-CaCl2 was determined by DTA. In the EuCl3-CaCl2 system, an incongruent compound EuCl3·3CaCl2 , a peritectic point at 570 ℃, containing EuCl3 45.4%(in mole per cent) and an eutectic point at 522 ℃, containing EuCl3 66.8%(in mole per cent) were obtained.
