Cerium Oxide is mainly using for:

a, as the most efficient glass polishing agent for precision optical polishing in glass industry;

b, decolorizing glass by keeping iron in its ferrous state in glass industry;

c, blocking out ultra violet light in the manufacturing of medical glassware and aerospace windows;

d, preventing polymers from darkening in sunlight and to suppress discoloration of television glass;

e, applied to optical components to improve performance.

F, high purity Cerium Oxide is also used in phosphors and dopant to crystal.
