In theSmCl_3-PbCl_2 system, an incongruent compound 3SmCl_3-PbCl_2, an eutectic point at 452℃containing 33.0 mol-% SmCl_3 and a peritectic point at 465℃ containing 42.0 mol-%SmCl_3 were obtained. In the SmCl_3-PbCl_2-CaCl_2 system, 4 liquiduses corresponding to theprimary crystallization of SmCl_3, PbCl_2, CaCl_2, and 3SmCl_3·PbCl_2, respectively, 5unvariant lines related to the secondary crystallization, a ternary eutectic point at 396℃ con-taining 29.5 SmCl_3 and 58.0 PbCl_2 by mol-% and a ternary peritectic point at 417℃ con-taining 36.0 SmCl_3 and 50.0 PbCl_2 by mol-% were found. Two reactions corresponding to 4phase equilibriums are L=CaCl_2+PbCl_2+3SmCl_3·PbCl_2 and L+SmCl_3=CaCl_2+3SmCl_3·PbCl_2.
