The development of cerium oxide for polishing.

China is rich in rare earth resources, and the reserves of industrial cerium resources reach about 18 million tons, which provides a good condition for the development and production of CeO2 polishing materials. At present, CeO2 polishing material has achieved a breakthrough in many aspects, and has become the primary choice of chemical mechanical polishing. Lens, optical fiber, optical components, for example, art glass, electronic glass, such as polishing, because the polishing material cutting ability is strong, high precision polishing, polishing time is short, and the advantages of operating environment clean, and other polishing materials polishing effect is good, often known as the "king of the polishing powder", has the very broad application prospects.
