摘要： The production of UF.sub.6 in which UF.sub.4 is reacted with air or oxygen in the presence of a catalyst at 500.degree. to 700.degree.C. The solid byproduct of this reaction is reduced with hydrogen in the presence of a catalyst at 400.degree. to 600.degree.C. Fresh UO.sub.3 may also be reduced with hydrogen in the same reactor as UO.sub.2 F.sub.2. The reduction product or products are reacted with hydrogen fluoride at 400.degree. to 600.degree.C, producing UF.sub.4 which would be recycled for further reaction to produce UF.sub.6.
