Abstract

The viscosities of 16 compositions of the potassium chloraluminate systems containing 3.8–57.2 mol % ZrCl₄ and 5.4–30.2 mol % HfCl₄ were determined in the temperature range 563–663 K. Their temperature dependences are presented. The binary chloraluminate mixtures containing HfCl₄ additives have the highest viscosity, and the binary mixtures with ZrCl₄ have the lowest viscosity. The viscosity of the three-component system has an intermediate value. The results can be used for the separation of zirconium and hafnium tetrachlorides.

KAlCl4–ZrCl4–HfCl4 盐熔体的粘度

摘要

含 3.8–57.2 mol% ZrCl ₄和 5.4–30.2 mol% HfCl ₄的氯铝酸钾系统的 16 种组合物的粘度在 563–663 K 的温度范围内测定。显示了它们的温度依赖性。含有HfCl ₄添加剂的二元氯铝酸盐混合物粘度最高，而含有ZrCl ₄的二元混合物粘度最低。三组分体系的粘度具有中间值。结果可用于锆和四氯化铪的分离。
