Cerium Oxide, also known as cerium(IV) oxide, ceric oxide, ceria, or cerium dioxide,
is an oxide of the rare earth metal cerium. It is a pale yellow-white powder with the chemical formula CeO2.

Cerium(IV) oxide is used to polish glass and stones, in ceramics, to sensitize photosensitive glass, as a catalyst and as a catalyst support, in lapidary as an alternative to "jeweller's rouge". It is also known as "optician's rouge".

It is also used in the walls of self-cleaning ovens as a hydrocarbon catalyst during the high-temperature cleaning process.
