摘要: 用DTA和X射线衍射方法研究了 SmCl_3-CaCl_2及SmCl_3-LiCl二元体系相图.发现前者属于简单低共熔型,低共熔点e_1为55.8mol%SmCl_3,545℃;后者属于有化合物分解的相图类型,该异分熔点化合物为Sm_2LiCl_7,分解温度434℃,转熔点p组成为39.0mol%SmCl_3.低共熔点e_2为31.5mol%SmCl_3,395℃。

Abstract:The phase diagrams of binary systems SmCl_3-CaCl_2 and SmCl_3-LiCl was determined by DTA and X-ray diffraction analysis. The system SmCl_3-CaCl_2 is of a simple eutectic type with eutectic point of 55.8 mol-% SmCl_3 at 545℃. The system SmCl_3-LiCl is of the type with incongruent melting phase 2SmCl_3·LiCl at peritectic point 434℃ and with eutectic point of 31.5 mol-% SmCl_3 at 395℃.
