Abstract
Phase equilibrium studies were carried out on the system UO2(NO3)2−HNO3−H2O between the temperatures of −10 °C and +49.1 °C over a wide concentration range of both UO2(NO3)2 and HNO3. No phase separation occurred above 49.1 °C for the concentrations studied. The three hydrates of UO2(NO3)2 were identified in the solid phase, and a new complex of UO2(NO3)2, possibly UO2(NO3)2.3HNO3, was separated as the solid phase at higher nitric acid concentrations.Keywords
