The development of cerium oxide

Development history of cerium oxide:

1. In the 1930s, rare earth oxides as polishing powders were first used to polish glass in Europe. During world war ii, rare earth polishing powders were quickly successful in polishing precision optical instruments. Because of the advantages of rare earth polishing powder such as high polishing efficiency, good quality and little pollution, it has aroused the research enthusiasm in the west. In this way, rare earth polishing powder to replace the traditional polishing powder trend developed rapidly.

2. In the 1990s, there are more than 30 kinds of standardized and serialized products.

3. At present, the main domestic brands are chute cerium oxide polishing powder and giambi cerium oxide polishing powder, etc. The annual production capacity of rhodia company in France is more than 2,200 tons, is the world's largest rare earth polishing powder manufacturers.
