High purity cerium oxide / rare earth polishing powder with lowest price
Cerium oxide polishing powder is widely used in glass polishing, and has the advantages of strong cutting force, short polishing time, long service life and high polishing precision. The cerium oxide polishing powder is classified into low enthalpy, medium bismuth and sorghum polishing powder according to the content of cerium oxide, and its cutting force and service life are also low to high.
The main component of cerium oxide polishing powder is cerium oxide (CeO2), followed by cerium oxide (La2O3), cerium oxide (Pr2O3), lanthanum oxyfluoride (LaOF), and also contains trace amounts of silica, alumina and calcium oxide.
