It is precipitated during production by adding aqueous ammonium hydroxide after uranium extraction by tertiary amines in an organic kerosene solvent. This precipitate is then thickened and centrifuged before being calcined to uranium oxide. Canadian practice favours the production of uranium oxide from ammonium diuranate, rather than from uranyl nitrate as is the case elsewhere.
Ammonium diuranate was once used to produce colored glazes in ceramics.
