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.[1] Along with ammonium diuranate it was a component in early yellowcakes.[2] The ratio of the two compounds is determined by process conditions; however, yellowcake is now largely a mix of uranium oxides.[3]
