Cerium oxide, a material suitable for glass polishing

The rare earth polishing material used in industry is the oxide of rare earth element cerium (CE) -- cerium oxide, which is used as polishing material. Practice has proved that the polishing effect of cerium rare earth polishing powder is better than that of other metal oxides, and it is currently known as the "king of polishing powder". Cerium rare earth polishing materials are more common in our daily life, such as optical lens, mobile phone panel, tablet computer, LCD display, watch shell, jewelry, etc., the surface is smooth as a mirror, is the result of rare earth polishing materials fine grinding. Rare earth polishing powder with cerium oxide content can be divided into two categories: one is high cerium polishing powder, as the name implies, cerium oxide content is high, and the higher the grade of cerium oxide, the stronger the polishing ability, mainly used for quartz, optical lens and other hard glass long time cycle polishing. The other is low cerium polishing powder, the content of cerium oxide is low, and cheap, mainly because of its polishing ability can be completely comparable with high cerium polishing powder, but the life is short, mainly used for plate, picture tube glass polishing. Rare earth polishing powders are ultrafine powders whose particle size and distribution affect the properties. Rare earth polishing powder can be divided into nanoscale rare earth polishing powder, submicron rare earth polishing powder, micron rare earth polishing powder 3 categories. The most commonly used is micron rare earth polishing powder, which is mostly used for rough grinding in the early stage of glass processing. The submicron rare earth polishing powder is mainly used in the field of liquid crystal display and computer optical disc, which is favored by the market. Nanoscale rare earth polishing powder has come into being, and modern technology is changing with each passing day. Its application prospect is immeasurable.
