Cerium Oxide Polishing Powder also called Cerium Polishing Powder and Rare Earth Polishing Powder is a high-performance polishing powder suitable for various kinds of glass. It reacts with the surface to produce a complex Cerium-Oxygen-Silica compound softer than glass, this softer surface layer is easily used to produce the final surface. Various grades of Cerium Oxide Polishing Powder are widely applied in flat glass, CRT, LCD, TFT glass, mirrors, glasses, optical glass, lens, and many other fields of the glass industry.

Type

1. Cerium oxide (CeO2), obtained from the separation of mixed rare earth salts (w(CeO2)=99%)
2. Mixed rare earth hydroxide (RE(OH)3), which is rare earth concentrate (w (REO)≥50%) Intermediate raw material after chemical treatment (w(REO)=65%, w(CeO2)≥48%)
3. Mixed rare earth chloride (RECl3), extracted and separated from mixed rare earth chloride Obtained less europium chloride rare earth (mainly containing La, Ce, Pr and Nd, w(REO)≥45%, w(CeO2)≥50%)
4. High-grade rare earth concentrate (w(REO)≥60 %, W(CeO2)≥48%)
