摘要

测定了氯化钆加入量在0 ~ 23mol %范围内时，氯化钆-GdCl3熔融体系的电导率随温度和GdCl3浓度的变化。考虑到混合物摩尔体积的可加性，计算了熔融GdCl3-LiCl体系的摩尔电导率。得到的温度依赖关系可以用arrhenius型方程近似表示。有效活化能Ea随GdCl3含量的增加而增大。用差示扫描量热法测定了所研究体系的液相温度。记录了氯化锂- gdcl3氯化物熔体的高温拉曼光谱。此外，还测量了加入1mol % Gd2O3的0.77LiCl-0.23GdCl3熔融体系的电导率。研究表明，氧化钆的加入使氯化物熔融体系的电导率降低，液相温度升高

Electrical conductivity of GdCl3-LiCl and GdCl3-LiCl-Gd2O3 molten systems

The electrical conductivity of LiCl-GdCl3 molten systems with the gadolinium chloride additions ranging from 0 to 23 mol% was measured depending on both the temperature and concentration of GdCl3. The molar electrical conductivity of the molten GdCl3-LiCl system is calculated taking into account the assumption of additivity of the molar volume of the mixture. The obtained temperature dependencies can be approximated by Arrhenius-type equation. The effective activation energy Ea increased with the GdCl3 content. The liquidus temperatures of the studied systems were determined by differential scanning calorimetry. The high-temperature Raman spectra of LiCl-GdCl3 chloride melts were recorded. In addition, the electrical conductivity of 0.77LiCl-0.23GdCl3 molten system with 1 mol% of Gd2O3 was measured. The investigation demonstrates that the addition of gadolinium oxide results in a decrease of the electrical conductivity of the chloride molten system and growth of its liquidus temperature
