Abstract: Concentrated anion-deficient salt solutions are prepared of the actinide oxides, PuO.sub.2, UO.sub.2, UO.sub.3 and U.sub.3 O.sub.8 by dissolving one or more oxides in an aqueous solution of thorium nitrate at a concentration of 4 molar or greater and at a temperature of 60.degree. C. or more. Anion-deficient salt solutions of actinide metals so produced are useful as starting materials for the manufacture of ceramic nuclear fuel particles by the sol-gel process.
