A dry process for the preparation of fluoride derivatives of uranium of the type (UF/sub 4/)/sub z/R/sub x/F/sub y/, R representing a metal selected from the group consisting of alkaline metals, rare earth alkaline metals, and lead, is described. The preparation consists of subjecting a uranate of one of the metals to the action of a reducing agent and of hydrofluoric acid. The reaction conditions sre chosen to obtain complete reduction of hexavalent uranium into tetravalent uranium and maximum fluoridation of the uranate used as the starting material. The reduction may be carried out between 250 and 850 deg C, however, a temperature between 500 and 600 deg C is preferable. The reducing agent is selected from hydrogen, carbon monoxide, methane, lighting gas, and ammonia. The process may be carried out in either a fixed or fluidized bed wherein the uranate particles for the latter are between 75 and 400 microns. (N.W.R.)
