Abstract

The reactions of oxygen and oxygen-containing gas mixtures (Ar–O₂, O₂–H₂O, and Ar–O₂–H₂O of various composition) with chloride melts containing uranium(III) ions are studied. Experiments are carried out in molten LiCl at 750°C and a LiCl–KCl eutectic mixture at 550 and 750°C. The uranium content in the melts was varied in the range 0.3–3.5 wt %. The effects of the oxygen to uranium molar ratio and the gas phase composition on the degree of precipitation of uranium from the melt and the composition of the formed products are studied.

氧气与三氯化铀在熔融碱金属氯化物中的反应

摘要

研究了氧气和含氧气体混合物（各种成分的Ar-O ₂、O ₂ -H ₂ O 和 Ar-O ₂ -H ₂ O）与含有铀 (III) 离子的氯化物熔体的反应。实验在 750°C 的熔融 LiCl 和 550 和 750°C 的 LiCl-KCl 共晶混合物中进行。熔体中的铀含量在 0.3-3.5 重量％的范围内变化。研究了氧与铀的摩尔比和气相组成对铀从熔体中沉淀的程度和形成的产物组成的影响。
