Usage:
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.
Packing: In plastic woven bags of 50kgs with inner plastic bags, or soft container bags of 250 or 500kgs.
Description: Cerium Oxide is a kind of red or light yellowish powder. Lt is mainly used as the glass decoloring and the glass polishing powder. Lt is also used as the raw materials in producing metal cerium. High purity cerium oxide is very important in the applications of Rare Earth fluorescent materials.
