cerium oxide

Cerium oxide is an inorganic compound. In terms of appearance, it usually presents pale yellow or tan. Its chemical properties are relatively active and it has good chemical reaction activity. Cerium oxide has excellent performances in multiple fields. In the field of materials, it is a high-quality polishing material that can make the surface of objects smooth and flat; in the chemical industry, it is often used as an efficient catalyst to accelerate the chemical reaction process; in the glass industry, it can significantly enhance the corrosion resistance of glass and improve its optical properties. The application prospect of cerium oxide is very broad.
