Fine Grade Cerium Oxide CeO2 Glass Polishing Powder CAS 1306-38-3
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.
It is suitable for optical spherical glass with abrasion less than
100, flat glass polishing, such as quartz glass; optical slow speed polishing
1. Chemical properties: TREO>99%, CeO2/TREO=99.9%
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.
(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.
