It is an important rare earth metal oxide with many important applications. Its formula is usually written as (La_1-x Ce_x) O_2-x/2, where 0 < x < 1 represents the molar fraction of lanthanum oxide and cerium oxide in lanthanum and cerium oxide. First, it is a good oxidizing agent and is often used in areas such as catalysts and spark plugs. Secondly, it is also widely used in solid oxide fuel cells (SOFC). In addition, lanthanum and cerium oxide is often used in ceramic and glass materials. Other applications include catalysts, waste gas treatment catalysts.Specification:Product nameCerium OxideCerium OxideCerium OxideCerium OxideGrade99.999%99.99%99.9%99%CHEMICAL COMPOSITION    CeO2/TREO (% min.)99.99999.9999.999TREO (% min.)99999999Loss on ignition (% max.)1111Rare Earth Impuritiesppm max.ppm max.% max.% max.La2O3/TREOPr6O11/TREONd2O3/TREOSm2O3/TREOY2O3/TREO2222250502010100.10.10.050.010.010.50.50.20.050.05Non-Rare Earth Impuritiesppm max.ppm max.% max.% max.Fe2O3SiO2CaOPbOAl2O3NiOCuO1050305105520100100100.020.030.050.030.050.05ITEMSPECIFICATIONSTEST RESULTSCeO2/TREO(%,min)99.99999.999TREO(%,min)99.099.51RE Impurities(ppm/TREO,Max)La2O3 1.0Pr6O11 1.0Nd2O3 1.0Sm2O3 1.0Eu2O3 1.0Gd2O3 1.0Tb4O7 1.0Dy2O3 1.0Ho2O3 1.0Er2O3 1.0Tm2O3 1.0Yb2O3 1.0Lu2O3 1.0Y2O3 1.0Non-Re Impurities(ppm,Max)Fe2O3 5.0SiO2 31.0CaO 25.0Al2O3 5.0L.O.I 0.15%ApplicationCerium 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.We can provide 99%, 99.9%, 99.99%, 99.999% purity. Special requirements for impurities can be customized according to customer requirements.
