Abstract
The authors give results of thermodynamic calculations of the stability fields of uraninites with different oxygen coefficients in pure water at 25°C and atmospheric pressure. They have also calculated the ionic solubilities of uraninites in aqueous solutions in the absence of complexing anions at different pH. They discuss the forms in which uranium is present in solutions, and the stabilities of anhydrous and hydrated uranium oxides. Finally, they draw conclusions regarding migration and deposition of uranium from natural aqueous solutions in the supergenesis zone.
