摘　　要：利用DTA研究了SmCl_3-SrCl_2-MgCl_2三元体系相图。发现它有对应Smal_3、SrCl_2、MgGl_2、SmSr_3Cl_9的四个液相面,五条二次结晶线,一个三元低共熔点E(41.8mol％ SmCl_3,30.7mol％SrCl_2,500℃),一个三元转熔点P(32.0mol％ SmCl_3,39.3mol％ SrCl_2,520℃)。对应的两个四相平衡反应为 L_HSmCl_3+SmSr_3Cl_9+MgCl_2The phase diagram of ternary system SmCl_3-SrCl_2-MgCl_2 has been investigated by DTA, There are four surfaces corresponding to the primary orystallization of SmCl_3, SrCl_2, MgCl_2, SmSr_3Cl_9 respectively and five univariant Lines related to the secondary crystallization. Ternary euteotio point E (41. 8mol ％ SmCl_3, 30. 7mol ％ SrOl_2, 500℃) and ternary periteotio point P(32. 0 mol ％ SmCl_3, 39. 3 mol ％ SrCl_2, 520℃) were found. Two equilibrium reaetions with four phases, namely,L_ESmCl_3+SmSr_3Cl_9+MgCl_2L_P+SrCl_2SmSr_3Cl_9+MgCl_2
