Cerium Oxide, also called Ceria, is widely applied in glass, ceramics, and catalyst manufacturing. In the glass industry, it is considered to be the most efficient glass polishing agent for precision optical polishing. It is also used to decolorize glass by keeping iron in its ferrous state. The ability of Cerium-doped glass to block out ultraviolet light is utilized in the manufacturing of medical glassware and aerospace windows. It is also used to prevent polymers from darkening in sunlight and to suppress the discoloration of television glass. It is applied to optical components to improve performance. High purity Ceria is also used in phosphors and dopants to crystal.
