摘要： 用交流电桥法测定了熔融KCl-NaCl(1:1摩尔)-RECl3的电导。比电导的温度函数表达式如下: κ=A+B(t-700) κ:比电导(Ω-1·cm-1);t:温度(700—850℃); A、B:本文给出的常数。讨沦了实验值与计算值的偏差,当稀土氯化物在熔体中的浓度为10—50重量百分数时可能形成了络合物。

Abstract: The electric conductivities of molten KCl-NaCl (1:1mol)-RECl3 weremeasured by the A.C.bridge method. The following empirical expression ofthe specific conductivity κ of the melt was obtained as a function of tem-perature:κ=A+B(t-700) where t is temperature (from 700℃ to 850℃), A and B are constant givenin the paper. The deviation of the obtained values from the calculated (forthe concentration of rare earth chlorides 10-50wt%) was discussed in viewof the possible formation of a complex.
