Abstract

The oxidation of UN and UC in a field of microwave radiation in air at atmospheric pressure was studied. The influence of the crucible material on the extent of oxidation of UN and UC was examined. Under the influence of a microwave field with a power of 800 W and a frequency of 2.45 GHz, under definite conditions, heating of UN and UC to ~993 K is observed with their oxidation in air to U3O8. For fast (15–20 min) and safe (without fires and explosions) oxidation of UN and UC, crucibles made of quartz and carbon ceramics are the best.
