Sodium diuranate, Na2U2O7·6H2O, is a uranium salt also known as the yellow oxide of uranium. 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.
Sodium uranate may be obtained in the amorphous form by heating together Urano-uranic oxide and sodium chlorate; or by heating sodium uranyl acetate or carbonate. The crystalline form is produced by adding the green oxide in small quantities to fused sodium chloride, or by dissolving the amorphous form infused sodium chloride and allowing crystallization to take place. It yields reddish-yellow to greenish-yellow prisms or leaflets.
Uses
A uranium glass bowl in the shape of a cat, on top of a Fiestaware plate, both previous uses of Sodium diuranate.
In the past it was widely used to produce uranium glass or vaseline glass, the sodium salt dissolving easily into the silica matrix during the firing of the initial melt.
It was also used in porcelain dentures to give them a fluorescence similar to that of natural teeth and once used in pottery to produce ivory to yellow shades in glazes. It was added to these products as a mix with cerium oxide.[disambiguation needed] The final uranium composition was from 0.008 to 0.1% by weight uranium with an average of about 0.02%.
