Rare Earth Polishing Powder KP2003 1.0-2.0um For Polishing Of Optical Filters
Name: Rare earth polishing powder, cerium oxide polishing powder Type: KP2003
D50: 1.0-2.0um TREO: ≥90%
Description: The main component of rare earth polishing powder is CeO2. According to the amount of CeO2, cerium polishing powder can be divided into two categories: one is the high-quality and high-quality cerium polishing powder with high CeO2 content, generally CeO2 / TREO ≥ 80%; the other is the low-cost low-ce polishing powder with low CeO2 content, whose cerium content is about 50%, or less than 50%. The rest is composed of La2O3, Nd2O3 and Pr6O11. As for ceria polishing powder, the higher the grade of ceria is, the greater the polishing ability is, and the longer the service life is. Especially when the hard glass is circularly polished for a long time (quartz, optical lens, etc.), it is better to use high-grade ceria polishing powder.
