Cerium oxide powder (CeO2 powder) is a white or pale yellow powder. It is used as a polishing material, catalyst, catalyst carrier (assistant), ultraviolet absorber, fuel cell electrolyte, automobile exhaust absorber, electronic ceramics, etc. According to the purity, it can be divided into: low purity (the purity is not higher than 99%), high purity (99.9% ~ 99.99%), and ultra-high purity (over 99.999%). It can also be divided into coarse powder, micron level, submicron level, and nanometer level, according to the particle size. Get a Quote Now!

Synonyms: Cerium(IV) Oxide, Cerium Dioxide

Typical application:

  1. Cerium polishing powder is widely used in the polishing of the camera, camera lens, TV picture tube, glasses, etc. It has the advantages of fast polishing speed, high finish, and long service life.
  2. Cerium oxide and neodymium oxide are the main rare earth elements used for glass decolorization. Rare earth glass decolorizer can not only improve the efficiency, but also avoid the pollution of white arsenic. Ceria has the advantages of high temperature stability, low price and no absorption of visible light.
  3. Rare earth ions have stable and bright colors at high temperature. They are used to mix in the material liquid to make various colors of glass. Neodymium, praseodymium, erbium, cerium and other rare earth oxides are excellent glass colorants.
  4. Cerium oxide is added to daily glass, such as building and automobile glass and crystal glass, which can reduce the transmittance of ultraviolet light.
