Sodium uranate or Yellow uranium oxide, a uranium compound with the chemical formula Na2O (UO3)2·6H2O is a yellow orange powder once used in pottery to produce ivory to yellow shades in glazes. It was also used in porcelain dentures to give them a fluorescence similar to that of natural teeth. It was added as a mix with cerium oxide. The uranium composed from 0.008 to 0.1% by weight uranium with an average of about 0.02%. The practice appears to have stopped in the late 1980s.

The alkaline process of milling uranium ores involves precipitating sodium uranate from the pregnant leaching solution to produce the semi-refined product referred to as yellowcake.
