Reaction Steps

In greater detail, one representative method of preparing uranium dioxide from uranium hexafluoride has uranium hexafluoride reacted with water to hydrolyze the fluoride and form a water solution of uranium oxyfloride and an acid. This water solution is reacted wtih ammonia to yield a precipitate of ammonium diuranate in a slurry. The ammonium diuranate slurry is converted to a dry particulate form of uranium dioxide by heating in wet hydrogen which achieves partial defluorination and reduction of the ammonium diuranate to uranium dioxide.
