Rare Earth Polishing Powder 2.0um Cerium Oxide Precision Polishing

The polishing process that uses cerium oxide is known as "chemical mechanical polishing" or "CMP." As its name suggests, this process does not simply use the polishing material to mechanically abrade the surface of the glass: there is also a chemical action whereby the cerium oxide smooths out the microscopic bumps and indentations on the glass surface.

【Application】
It is suitable for optical spherical glass with abrasion 100-150. Cerium oxide abrasive is more used in the optical glass polishing. It is used as grains abrasive in suspension or fixed abrasive (pellets); these pellets are manufactured from a mixture made of cerium oxide abrasive and a organic binder.


【Specification】

1. Chemical properties: TREO>94%, CeO₂/TREO=60-70%,La₂O₃/TREO=20-30%
2. Color:light yellow
