| 摘要: 借助于DTA测定了YbCl3-CaCl2-MgCl2三元体系液相限.发现本体系有对应于YbCl3、CaCl2、MgCl2和不稳定化合物X的四个液相面,五条二次结晶线,一个三元低共熔点E(38.0wt%YbCl3,31.0wt%CaCl2,31.0wt%MgCl2;556℃)和三元转熔点P'(45.5wt%YbCl3,28.0wt%CaCl2,26.5wt%MgCl2;600℃). |

| Abstract: The liquidus of ternary system YbCl3-CaCl2-MgCl2 has been investigated by means of DTA. It was found that there arc four surfaces coryesponding to the primary crystallization of YbCl3, CaCl2, MgCl2 and unstable compound X respectively, and five univariant curves to the secondary ctystallization. The temperature of the ternary cutectic, composed of 38.0wt%YbCl3, 31.0wt% CaCl2, 31.0wt% MgCl2, was determined to be 556℃. The temperature of the ternary peritecti-like, composed of 45.5wt% YbCl3, 28.0wt% CaCl2, 26.5wt% MgCl2, was observed to be 600℃. |
