Application:

1. as the most efficient glass polishing agent for precision optical polishing in glass industry;

2. decolorizing glass by keeping iron in its ferrous state in glass industry;

3. blocking out ultra violet light in the manufacturing of medical glassware and aerospace windows;

4. preventing polymers from darkening in sunlight and to suppress discoloration of television glass;

5. applied to optical components to improve performance.

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