Application
Cerium oxide, also known as ceria, is a rare earth metal oxide with several significant applications:
1. **Polishing Agent**: Cerium oxide is widely used as a polishing agent, particularly in the manufacturing of glass, including precision optical lenses, mirrors, and television screens. Its fine abrasive properties make it ideal for removing fine scratches and achieving a high level of polish.
2. **Catalyst and Catalyst Support**: In the chemical industry, cerium oxide is used as a catalyst or a catalyst support. It is particularly effective in catalyzing the oxidation of carbon monoxide and hydrocarbons, which is useful in automotive exhaust systems to reduce harmful emissions.
3. **Glass Additive**: Cerium oxide is added to glass to block ultraviolet light and prevent glass from discoloring under prolonged exposure to sunlight. This is particularly useful in the production of automotive glass and glass used in buildings.
4. **Ceramics**: In ceramics, cerium oxide is used to sensitize photosensitive glass and to decolorize glass by offsetting the green tint of iron impurities.
5. **Solid Oxide Fuel Cells**: Cerium oxide is used in the electrolytes of solid oxide fuel cells due to its high oxygen ion conductivity.
6. **UV Absorber**: Due to its ability to absorb UV light, cerium oxide is used in various applications, including sunscreen and cosmetics, to protect against UV radiation.
7. **Semiconductors and Electronics**: In the semiconductor industry, cerium oxide is used for chemical mechanical planarization, a process critical in the manufacture of integrated circuits.
8. **Oxygen Sensor**: Cerium oxide's unique ability to release and absorb oxygen makes it useful in oxygen sensors and in controlling oxygen levels in various processes.
These applications utilize the unique chemical and physical properties of cerium oxide, such as its abrasive qualities, UV absorption, and catalytic activity.
