Cerium oxide is an inorganic substance, chemical formula CeO2, light yellow or yellowish brown auxiliary powder. Density 7.13g/cm3, melting point 2397℃, insoluble in water and alkali, slightly soluble in acid. At 2000℃ and 15MPa pressure, cerium oxide can be reduced by hydrogen to obtain cerium trioxide. When the temperature is free at 2000℃ and the pressure is free at 5MPa pressure, cerium oxide is yellowish, reddish, and pink. Its performance is to do polishing material, catalyst, catalyst carrier (auxiliary), ultraviolet absorber, fuel cell electrolyte, automobile exhaust absorber, electronic ceramics and so on.

Quality index：
According to the purity is divided into: low purity: purity is not higher than 99%, high purity: 99.9%~99.99%, ultra-high purity 99.999% or more.
According to the particle size, it is divided into: coarse powder, micron level, sub-micron level and nano level.
Safety description: The product is toxic, tasteless, non-irritating, safe and reliable, stable performance, no chemical reaction with water and organic matter, is a high-quality glass clarifying agent, decolorizing agent and chemical additives.
Application:
1. Oxidizing agent. Catalysts for organic reactions. Steel analysis for rare earth metal standard sample. REDOX titration analysis. Decolorized glass. Glass enamel sunscreen. Heat resistant alloy.
2. It is used as a glass industry additive, as a plate glass grinding material, and can also play an anti-ultraviolet role in cosmetics. It has been expanded to the grinding of glasses glass, optical lenses and picture tubes, which plays the role of decolorization, clarification, absorption of ultraviolet rays and electronic lines of glass.
3. Rare earth polishing powder has the advantages of fast polishing speed, high finish and long service life. Compared with traditional polishing powder – iron red powder, it does not pollute the environment and is easy to remove from the stick.General rare earth glass polishing powder mainly uses cerium-rich oxide. Cerium oxide is an extremely effective polishing compound because it can be used to polish glass simultaneously in the form of chemical decomposition and mechanical friction. Rare earth cerium polishing powder is widely used in the polishing of cameras, camera lenses, TV picture tubes, eye lenses, etc.
