Because of cerium series rare earth polishing powder has excellent chemical and physical properties, so widely used in industrial products, polishing, such as in various optical devices, television kinescope glass, optical glass lens, oscilloscope tube, plate glass, semiconductor wafer and metal precision products such as polishing.
Cerium is a rare earth polishing powder, which is suitable for high speed polishing of precise optical lens.The polishing powder has good performance and good polishing effect, because the price is higher and the domestic use is less.Of cerium series rare earth polishing powder, mainly applied optics instrument of medium small spherical lens high-speed polishing precision, the polishing powder compared with ceric powder, can make the liquid concentration by 11% of polishing powder, polishing rate increased by 35%, the products finish level can be improved, the service life of the polishing powder can be increased by 30%.At present, the domestic use of this polishing powder is not enough, and it is still needed to develop new USES in the future.Low cerium rare earth polishing powder is suitable for the polishing of TV tube, eye lens and flat glass.
