Abstract
Uranium tetrafluoride is produced by treating a solution of an oxygen-containing uranium compound, e.g. sodium uranate, or uranyl sulphate, chloride, or acetate with hydrochloric or sulphuric acid, and a reducing agent, e.g. solid stannous chloride, or zinc, at say 90-100 DEG C, and treating the resultant uranous salt solution with a metal fluoride, or hydrogen fluoride, say 30 per cent hydrofluoric acid in 100 per cent excess, to precipitate the tetrafluoride 25-100 per cent excess hydrochloric or sulphuric acid over that necessary for the reduction may be used. The fluoride-precipitating agent should be added rapidly at or near the boiling point of the solution. The uranium tetrafluoride is washed, filtered and dried, first at 100-120 DEG C, then at 350-450 DEG C in vacuo or in an inert gas. It may be reacted with fluorine to yield the hexa-fluoride.
