Oxidation of Uranium Dioxide (UO2)

Article metrics

Abstract

IN connexion with earlier investigations on uranium oxides in this Institute, it was observed that uranium dioxide (UO2) can react with oxygen at so low a temperature as 120° C. To obtain more exact information about this low-temperature oxidation of UO2, the oxide was heated in purified oxygen at different temperatures from 100° to 265° C. and the reaction products examined by the X-ray powder method1.
