Product Specification

Customized Cerium Oxide Polishing Powder For Optical Glass

GONA offers a wide range of customized, application-based cerium oxide glass polishing product formulations with a tightly controlled particle size distribution and excellent suspension characteristics to ensure a consistent polishing performance from batch to batch.

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 80-120, flat glass polishing, such as K9 glass.

【Specification】

      1. Chemical properties: TREO>94%, CeO₂/TREO= 65-70%,La₂O₃/TREO=30-35%,Pr₆O₁₁/TREO%<3%

      2. Color:red brown

      3.PSD: D50=1.0-1.4um,D99<6um

【Product features】

(1) Strong versatility: the product has uniform particle distribution, can meet the requirements of smoothness and abrasion, and has a wide range of applications.

(2) No impurities: multiple screening procedures are adopted to remove impurities to ensure no scratches after use.

(3) Stable suspension: additives are added to keep the product in a good suspension state and easy to clean.

【Application methods】

     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.

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