Cerium Oxide Product Elucidation
CAS No.: 1306-38-3
Appearance:Yellow to tan
Solubility: Insoluble in water, moderately soluble in strong mineral acids
Stability: Slightly hygroscopic
Application: also called Ceria, is widely applied in glass, ceramics and catalyst manufacturing.
In 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 ceriumdoped glass to block
out ultra violet 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 discoloration of television glass. It is applied to
optical components to improve performance. High purity Ceria are also used in phosphors and dopant to crystal.
