Description

Cerium (IV) oxide (chemical formula: CeO2) is an oxide of the rare earth metal cerium. It appears as yellow-white powder. It is an important intermediate during the purification of the Ce element from the ores. It is mainly used in formulations in industry as a high-precision polishing agent for glass products. It can also be used in infrared filters, and used as an oxidizing compound in the catalytic converters as well as a replacement for thorium dioxide in the incandescent mantles. It can also be used as oxidation catalyst due to its interconvertibility, e.g. in oxidation of the natural gas in gas mantles. It can also be used as a mixed conductor due to its significant ionic and electronic conduction. It can be manufactured by the calcination of cerium oxalate or cerium hydroxide.
