1306-38-3 Optical Rare Earth Polishing Powder 0.5um CeO2
The main component of rare earth polishing powder is ceria, which
is generally classified according to the content of ceria. The
higher the content of ceria in polishing powder, the stronger the
polishing ability, the longer the service life and the higher the
corresponding price. On the contrary, the price of cerium will be
lower if the content of cerium is low. Its initial polishing
ability is basically the same as that of cerium products, but its
service life is short.
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.
