The possibility of purifying the metalized products of pyrochemical operations by removing the electrolyte by distilling off lithium chloride is checked experimentally. This study is performed in connection with the development of promising variants of an industrial method of metalizing uranium dioxide, which is the main component of the spent nuclear fuel after its voloxidation. The electrolyte was distilled from metalized pellets and powders based on uranium dioxide with their continuous evacuation at 700–900°C. It was found that the main component of the sublimates is lithium chloride; the content of rare-earth elements and uranium is very low. The distillation regimes where 98.8–99.9% of the LiCl can be removed from the metalized products were determined.

从二氧化铀金属化产物中蒸馏氯化锂

通过实验检查通过蒸馏除去氯化锂来去除电解液来纯化高温化学操作的金属化产物的可能性。这项研究是结合二氧化铀金属化工业方法的有希望的变体的开发而进行的，二氧化铀是废核燃料挥发后的主要成分。电解液是从基于二氧化铀的金属化球团和粉末中蒸馏出来的，它们在 700-900°C 下连续抽真空。发现升华物的主要成分是氯化锂；稀土元素和铀的含量很低。确定了可以从金属化产品中去除 98.8-99.9% 的 LiCl 的蒸馏方式。
