Description of product

Cerium Oxide, 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 Cerium-doped 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.

Our company produces cerium oxide for a long time, with an annual production capacity of 2000 tons. Our cerium oxide products are exported to China, India, USA, Korea, Japan and other countries. They are mainly used as precursors for preparing polishing fluid, additives for paints and ceramics, and glass decolorization. We have professional R&D teams and support OEM.
