Abstract

Equilibrium potentials of antimony in the KCl–PbCl₂–SbCl₃ melt are measured by the EMF method as a function of the temperature and the content of antinomy chloride. Empirical equations of isotherms and polytherms of equilibrium potentials of antimony are obtained. The arbitrary standard potentials of antimony in the molten mixture of potassium and lead chlorides are calculated. The changes in the Gibbs energy at the formation of antimony trichloride from elements in the melt under study are calculated. The separation factors of metals from alloys are assessed. These results suggest that the processes of separation of lead and antimony in chloride melts hold much promise.

钾和氯化铅混合物中锑的电极电位

摘要

通过EMF方法测量KCl–PbCl ₂ –SbCl ₃熔体中锑的平衡势，该温度是温度和氯化锑含量的函数。得到了锑平衡势的等温线和等温线的经验方程。计算了氯化钾和氯化铅熔融混合物中锑的任意标准电势。计算了由所研究的熔体中的元素形成三氯化锑时吉布斯能量的变化。评估了金属与合金的分离系数。这些结果表明，氯化物熔体中铅和锑的分离过程具有广阔的前景。
