Application
1. It is widely applied in glass, ceramics and catalyst manufacturing.
2. In glass industry, it is considered to be the most efficient glass polishing agent for precision optical polishing.
3. 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.
4. It is also used to prevent polymers from darkening in sunlight and to suppress discoloration of television glass
5. It is applied to optical components to improve performance. High purity ceria are also used in phosphors and dopant to crystal.
Preparation Method
Oxalate Precipitation Method: Cerium Chloride or Cerium nitrate liquor as raw material, use ammonia water to make the Ph down to 2, drop Oxalic acid subside the cerium oxalate, after thermo maturation, separate,washing, drying under 110°C, keep the temperature at 900~1000°C firing into Cerium Oxide. Ce2(C2O4)3→2CeO2+2CO2+4CO
