Important diuranates include ammonium diuranate ((NH₄)₂UO₄), sodium diuranate (Na₂UO₄) and magnesium diuranate (Mg₂UO₄), which together form part of some yellowcakes. These mixtures were sometimes referred to as uranium diuranate, but this term has fallen out of use. Others include potassium diuranate (K₂UO₄) the colouring agent used to produce the hue Webb’s Ivory in cased glassware, also called 'orange uranium' for the colors it yieded in oxidation, and barium diuranate (BaUO₄) used for making porcelain paints. Various other alkaline earth diuranates have been described, but as of yet have found commercial use; they are however of some interest in mineralogy.
