Sodium diuranate, also known as the yellow oxide of uranium, is an inorganic chemical compound with the chemical formula Na₂U₂O₇. It is a sodium salt of a diuranate anion. It forms a hexahydrate Na₂U₂O₇·6H₂O. Sodium diuranate is commonly referred to by the initials SDU. Along with ammonium diuranate it was a component in early yellowcakes. The ratio of the two compounds is determined by process conditions; however, yellowcake is now largely a mix of uranium oxides.
