1. Polishing Powder
Rare earth polishing powder has the advantages of fast polishing speed, high finish and long service life.
2.Rare earth decolorizer for glass
Cerium oxide for glass decolorization has the advantages of stable high temperature performance, low price and no absorption of visible light.
3. Glass coloring
Rare earth ions have stable and bright colors at high temperatures, and are used to be incorporated into the feed liquid to make glass of various colors. Rare earth oxides such as neodymium, praseodymium, erbium and cerium are excellent glass colorants.
4.Rare earth clarifier
Using cery to replace the traditional arsenic oxide as a glass clarifier, clear bubbles and trace color elements, and the preparation of a colorless glass bottle is significant, and the finished crystal is white, transparent, glass and heat resistant. It also eliminates the pollution of arsenic to the environment and glass.
