Gas-phase conversion of the U, Sr, Mo, and Zr oxides into water-soluble compounds in the NOx–H2O (vapor)–air atmosphere

详细

The gas-phase conversion of U₃O₈, MoO₃, SrO, and their mechanical mixtures, and also of ZrO₂ into water-soluble compounds in the NO_x–H₂O (vapor)–air atmosphere was studied. In the course of gas-phase conversion, U₃O₈ and SrO transform into water-soluble compounds (nitrates, hydroxonitrates), 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 NO_x–H₂O (vapor)–air atmosphere was demonstrated.
