Applications of polishing powder
Rare earth cerium oxide glass polishing powder is used in ceramics, to sensitize photosensitive glass, as a catalyst and as acatalyst support, to polish glass and stones, in lapidary as an alternative to "jeweller's rouge". It is also known as "optician's rouge".
Rare earth cerium oxide glass polishing powder is also used in the walls of self-cleaning ovens as a hydrocarbon catalyst during the high-temperature cleaning process.
While Rare earth cerium oxide glass polishing powder is transparent for visible light, it absorbs ultraviolet radiation strongly, so it is a prospective replacement of zinc oxide and titanium dioxide in sunscreens, as it has lowerphotocatalytic activity. However, its thermal catalytic properties have to be decreased by coating the particles with amorphous silica or boron nitride. The use of these nanoparticles, which can penetrate the body and reach internal organs, has been criticized as unsafe.
