Abstract
In a process for obtaining sinterable uranium oxide, uranium dioxide is made by reduction at 700 DEG to 1000 DEG C. and immediately oxidized at 700 DEG to 1000 DEG C. in an atmosphere containing water vapour but otherwise free of elemental or combined oxygen. The uranium dioxide preferably is made by dissociating and reducing ammonium diuranate at 700 DEG to 1000 DEG C., but may be made by reduction of uranium trioxide UO3), uranium trioxide hydrate, uranium oxide (U3O8), uranium peroxide (UO4) or non-stoichiometric uranium dioxide. The reduction may be in hydrogen, a mixture of an inert gas, e.g. nitrogen, and hydrogen, or in carbon monoxide. The oxidation may be in nitrogen or argon containing water vapour provided by passing the gas through water at 80 DEG C. The sinterable uranium oxide product has a composition between UO2.02 and UO 2.08. Examples are given.
