APPLICATIONS
Cerium oxide, also known as ceria, has several important applications due to its unique chemical properties. Here are some of its key uses:
1. Polishing Agent: Cerium oxide is widely used as a polishing agent, particularly for polishing glass, including mirrors, television screens, and optical lenses. Its fine particle size and chemical properties help achieve a smooth, defect-free surface.
2. Catalyst: It's used in various chemical processes as a catalyst. In automotive applications, cerium oxide is used in catalytic converters to reduce harmful emissions from internal combustion engines.
3. Glass Additive: In glass manufacturing, cerium oxide is added to improve the color and clarity of glass. It helps in decolorizing glass by offsetting the green tint that can be caused by iron impurities.
4. Ceramics: In ceramics, cerium oxide enhances color and strength. It's often used in glazes and decorative finishes.
5. UV Absorber: Due to its ability to absorb ultraviolet light, cerium oxide is used in coatings and plastics to prevent UV degradation.
6. Fuel Cells: It's used in solid oxide fuel cells (SOFCs) due to its ionic conductivity and oxygen storage capability.
7. Semiconductors and Electronics: In the semiconductor industry, cerium oxide is used for chemical mechanical planarization, a process essential for smoothing and finishing silicon wafers.
8. Oxygen Sensors and Storage: Its ability to store and release oxygen makes it useful in oxygen sensors and oxygen storage systems.
9. Radiation Protection: Cerium oxide nanoparticles can protect against radiation, making it a candidate for use in radiation therapy and radiological protection.
10. Biomedical Applications: There is growing interest in using cerium oxide nanoparticles for biomedical applications, including as antioxidants in therapeutic treatments.
Each of these applications leverages the unique chemical and physical properties of cerium oxide, making it a versatile and valuable material in various industries.
