摘要

研究了常压微波辐射下unc和UC在空气中的氧化作用。考察了坩埚材料对unc和UC氧化程度的影响。在功率为800 W，频率为2.45 GHz的微波场作用下，在一定条件下观察到UN和UC被加热到~993 K，并在空气中氧化成U3O8。对于UN和UC的快速（15-20分钟）和安全（无火灾和爆炸）氧化，石英和碳陶瓷制成的坩埚是最好的。

Determination of Conditions for the Oxidation of UN and UC under Microwave Irradiation

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.
