Abstract

Uranium tetrafluoride is prepared by heat treating uranyl oxalate in the absence of oxidizing gases at temperatures below 900 DEG C. to form uranium dioxide which is then treated with gaseous hydrogen fluoride at a moderate temperature, for example 100 DEG to 150 DEG C. The process can, if desired, be effected in a single stage in a rotary tube furnace, the first part of which serves to decompose the oxalate and the second part to fluorinate the oxide formed. The oxalate decomposition preferably takes place at 450 DEG to 600 DEG C., in a carbon dioxide atmosphere which may be obtained by recycling the off gases from the oxalate decomposition furnace. Suitable reaction vessel linings are aluminium, calcium fluoride or graphite or copper, nickel or precious metals. If the fluorination takes place in a separate apparatus a lining or polyfluoro-ethylene may be employed.
