Abstract
Gas-phase conversion of UC in NOx-air, NOx-H20 (vapor)-air, and HN03 (vapor)-air atmospheres in the temperature interval from 298 to 673 K was studied. In the course of the gas-phase conversion in an NOx-air atmosphere, UC transforms into uranium oxides and oxyhydroxides; uranyl nitrates and hydroxyni-trates are formed in smaller amounts. In NOx-H20 (vapor)-air and HN03 (vapor)-air atmospheres, the major conversion products are uranyl nitrate hydrates, with the nitration occurring at a lower temperature than in an NOx-air atmosphere.
