Application of Cerium Oxide
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.
Cerium oxide, also known as ceria, is a compound composed of the elements cerium and oxygen with the chemical formula CeO2. It is light yellow or white powder, relatively stable under normal conditions. Cerium oxide has a variety of applications, including:
1. Catalyst: Cerium oxide is used as a catalyst in many industrial processes, such as in the automotive industry for catalytic converters to reduce emissions and for the production of synthetic fuels.
2. Polishing agent: Cerium oxide is used as a polishing agent for glass and other materials. It is very effective at smoothing rough surfaces and removing scratches.
3. Fuel additive: It can be used as a fuel additive to promote cleaner and more efficient combustion of fuel.
4. Glass industry: Cerium oxide is used in the glass industry to produce high-quality glass because it can increase the refractive index and enhance the durability of the glass.
5. Solar cell production: Cerium oxide is used as a coating material for the production of solar cells. Overall, cerium oxide has many applications and it is an important compound in various industries due to its unique properties.
6.used as the glass decolorizing agent and the glass polishing powder. Also used as the raw material in making metal cerium. High purity Cerium dioxide is very important in the applications of rare earth fluorescent materials
