【摘要】 用DTA和X射线衍射方法研究了 SmCl₃-CaCl₂及SmCl₃-LiCl二元体系相图.发现前者属于简单低共熔型,低共熔点e₁为55.8mol%SmCl₃,545℃;后者属于有化合物分解的相图类型,该异分熔点化合物为Sm₂LiCl₇,分解温度434℃,转熔点p组成为39.0mol％SmCl₃.低共熔点e₂为31.5mol％SmCl₃,395℃。更多还原

【Abstract】 The phase diagrams of binary systems SmCl₃-CaCl₂ and SmCl₃-LiCl was determined by DTA and X-ray diffraction analysis. The system SmCl₃-CaCl₂ is of a simple eutectic type with eutectic point of 55.8 mol-％ SmCl₃ at 545℃. The system SmCl₃-LiCl is of the type with incongruent melting phase 2SmCl₃·LiCl at peritectic point 434℃ and with eutectic point of 31.5 mol-％ SmCl₃ at 395℃.更多还原
