Description
A whitish or pale yellow powder used as an abrasive, catalyst and as an ingredient in glass and glazes. As a commercial abrasive, ceric oxide is a brown color due to impurities. It is used to polish gemstones and glass, especially optical surfaces and automobile windshields. Ceric oxide is added to soda-lime mixtures as a decolorizer and to ceramics to increase opacity.
