Abstract
1,269,029. Metals by reduction in the presence of fluorides. COMMISSARIAT A L’ENERGIE ATOMIQUE. July 6, 1970 [July 11, 1969], No.32613/70. Heading C7D. A method of preparation of metals in the massive state from their oxides comprises heating a mixture in a non-oxidizing atmosphere by induction which mixture comprises the oxide to be reduced, an alkali or alkaline earth metal as reducing agent, and a fluoride of the reducing metal to act as solvent. Also present may be another alkali or alkaline earth metal fluoride miscible with the solvent and not reducible by the reducing metal. The reducing metal may be Ca or Mg, and the metal produced may be Ti, Zr, U, the actinides, or the lanthanides. When Ca constitutes the reducing metal CaF 2 is the solvent, which may be mixed with MgF 2 . A suitable apparatus is that shown in the figure, which may best be operated between 400 Kc/s and 10Mc/s and where U is produced from UO 2 or U 3 O 8 at a temperature of 1560-1620C. for 15-30 minutes under an atmosphere of argon, nitrogen or hydrogen. During the reaction, the mixture may be agitated. The method may be applied to the deoxidation of wastes such as shavings.
