What Should You Know about Cerium Oxide Polishing Powder

Cerium oxide polishing powder is widely used in glass polishing. It has the advantages of strong cutting force, short polishing time, long service life and high polishing precision. According to the content of cerium oxide, cerium oxide polishing powder is divided into low cerium, cerium, cerium polishing powder, cutting power.

As cerium-based rare earth polishing powder has better chemical and physical properties, it has been widely used in the polishing of industrial products, such as various optical glass devices, television picture tubes, optical glasses, oscilloscopes, flat glass, Semiconductor chips and precision metal products such as polishing.

Cerium rare earth polishing powder, is mainly used for high-speed precision optical lens polishing. The excellent performance of the polishing powder, polishing is better, due to higher prices, the domestic use of less. The cerium-based rare earth polishing powder is mainly used for high-speed polishing of moderate precision medium and small spherical lenses of optical instruments. Compared with the high-cerium powder, the polishing powder can reduce the liquid concentration of the polishing powder by 11% and the polishing rate by 35% Finish can be improved by one degree, polishing powder life can be increased by 30%.

Low cerium-based rare earth polishing powder, is suitable for television picture tubes, eyeglasses and flat glass polishing. In addition, other polishing powders are used to polish optical instruments, video cameras, and camera lenses, and the like, with the largest amount of polishing powder.

The main components of cerium oxide polishing powder are cerium oxide (CeO2), followed by La2O3, Pr2O3, LaOF, and trace amounts of silicon oxide, aluminum oxide and calcium oxide.

Is ceria poisonous?

The density of 7.13g / cm3. Melting point is 2397 °C. It is insoluble in water and alkali, slightly soluble in acid. The temperature is free from 2000 ℃, at 5Mpa pressure, cerium oxide was slightly yellowish red, and pink, its performance is to do polishing materials, catalysts, catalyst carriers (additives), UV absorbers, fuel cell electrolytes, automobile exhaust absorbers, electronic ceramics.

Uses:
1 It can be used for oxidant, organic reaction catalyst, steel analysis for rare earth metal standard, redox titration analysis, decolored glass, glass enamel sunscreens, heat-resistant alloy.
2 Used as a glass industry additive for plate glass grinding material, can also be used in cosmetics play a role in anti-UV. It has been expanded to the glasses, optical lenses, CRT grinding, from decolorization, clarification, the absorption of ultraviolet glass and electronic lines and so on.

3 The rare earth elements are used for the decolorization of glass, they are mainly ceria and neodymia. Rare earth glass bleaching agent can replace the traditional use of bletilla striata, not only to improve efficiency, but also to avoid the pollution of white snakehead. Cerium oxide is used for glass bleaching with high temperature performance, low price and does not absorb visible light and so on.
4 The use of cerium oxide can instead of the traditional arsenic as a glass clarifier to remove air bubbles and trace elements, the effect is notable in the preparation of colorless glass bottles, the finished product crystal fluorescent is white, good transparency, glass strength and heat resistance increased. It also eliminates arsenic pollution of the environment and glass.
