Large Particles classical Optical Polishing Powder

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.

Consequently, particles of glass clump together with particles of polishing material in the used slurry, making it difficult to remove the glass component. This is why conventional reclamation techniques either have an extremely low reclamation rate, or are prohibitively expensive. For these reasons, and because the substances used to carry out reclamation are themselves environmentally problematic, the existing methods pose problems that remain to be solved.


【Application】

It is suitable for optical spherical glass with abrasion less than 100, flat glass polishing, such as quartz glass; optical slow speed polishing.


【Specification】

1. Chemical properties: TREO>94%, CeO₂/TREO=60-70%
2. Color:light yellow
3.PSD: D50=1.2-1.6um,D99<10um

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.

【Product features】

(1) No impurities: multiple screening procedures are adopted to remove impurities to ensure no scratches after use.
(2) Stable suspension: additives are added to keep the product in a good suspension state and easy to clean.


【Application methods】

【Packing】 25kgs/poly-drum ,500kgs/pallet;It can be according to customers requirements.
