Abstract
Gas-phase conversion of U3O8, MoO3, SrO, ZrO2, and their mechanical mixtures into water-soluble compounds in an HNO3 (vapor)–air atmosphere was studied. In the course of the gas-phase conversion, U3O8 and SrO transform into water-soluble compounds (nitrates, hydroxynitrates), whereas MoO3 and ZrO2 undergo no changes. The principal possibility of separating U from Mo and Zr by gas-phase conversion of the oxides in the HNO3 (vapor)–air atmosphere was demonstrated.
