Gaseous volume oxidation (voloxidation) of uranium mononitride (UN) and uranium monocarbide (UC) was investigated in the "NOx-air" atmosphere in the temperature range 298–673 K. It was shown that UN can be converted into uranium water-soluble compounds using an alternative oxidation atmosphere based on NOX-gases. UO3 and uranyl nitrates are the main products of the reaction. Maximum degree of the UN conversion to water-soluble compounds equal to 80 % was observed at the temperature 565 K. Products of the UC conversion are uranium oxides and oxihydroxides. The observed degree of the UC conversion into water-soluble compounds was less then 20 %. [ABSTRACT FROM AUTHOR] |
