Abstract

1419492 Uranium carbide UNITED KING- DOM ATOMIC ENERGY AUTHORITY 19 Feb 1973 [2 Dec 1971] 56111/71 Heading C1A [Also in Division G6] Sintered uranium carbide particles and/or sintered plutonium carbide particles are prepared by precipitating an oxide-forming compound of uranium or plutonium or a mixture of oxideforming compounds of the metals in the form of gel particles containing carbon, and contacting the gel particles with a solution of a nickel compound in an organic solvent thereby providing nickel in the particles as a sintering aid. The organic solvent in which the nickel compound is dissolved may be used to dry the gel particles by azeotropic distillation, or the solvent may extract water from the gel particles. The solvent may be a chlorinated hydrocarbon such as trichloroethylene, perchloroethylene, carbon tetrachloride, or an alkanol such as nhexanol, 2-ethyl-hexanol or a mixture of aliphatic alcohols. Specified nickel compounds include nickel acetylacetonate, nickel oluate, nickel naphthenate or nickel 4-cyclohexyl butyrate. The particles are converted carbthermically into the corresponding carbides.
