Abstract
The oxidation behavior of uranium monocarbide was investigated at moderate temperatures at various partial pressures of oxygen from 5 to 152 mmHg. The oxidation of uranium monocarbide began between 225° and 250°C with a slight dependence on the oxygen pressure.Analysis of the oxidation curves and by X-rav diffraction patterns indicates that the final product U3O8 is formed in one-step. The present data agree well with the expression representing rate-controlling reaction at the surface:(1-c)1/3=1-kt, where c is the fraction of oxidation in time t, and k the reaction rate constant.The activation energy detemined for the oxidation process is 5.0 kcal/mol for low oxygen partial pressures (510 mmHg).
