Rare earth Cerium oxide polishinng powder
Rare earth Cerium oxide polishinng powder is a polishing material mainly made of cerium oxide powder and lanthanum oxide. Cerium oxide has excellent physical and chemical properties, and is therefore widely used in different industries.The main characteristics of cerium oxide polishing powder are fine particles, uniform color, good wear resistance and high temperature resistance. It can effectively remove stains, flaws, and oxide layers on the surface of objects, improve surface smoothness, and bring a bright appearance to objects.
Cerium oxide polishing powder is widely used in different fields. In the glass industry, it is commonly used for polishing glass products, such as glass lenses, glass instruments, etc. In the metal processing industry, it can be used for polishing and repairing metal surfaces, such as stainless steel products, aluminum products, etc. In addition, it can also be used for polishing materials such as ceramics, plastics, and stone.
