The direct reduction of in vacuum of UO/sub 3/ with C takes place at the relatively low temperatures of 350 to 400 tained C with charcoal and at 450 to 530 tained C when carbon obtuined from sugar is used. Previous observations of W. Biltz and H. Mllller (Z. anorg. u. allg. Ch.163, 245, 279 (1927)) that disscciation cccurs at temperatures above 430 tained C were confirmed and therefore such a dissociation cannot be stipulated as a preliminary phase of the direct reduction prccess. Diffusion of the C across the solid layer appears to be improbable because this oxide does not form carbide easily. Most probably, the reduction performed by the carbon oxide formed according to the reaction C + CO/sub 2/ = 2CO. The activation energy of the reduction by means of charcoal is 43 kcal/mol and by C from sugar 65 kcal/mol. The gaseous effluent of the reaction consists of CO/sub 2/. (TTT)
