Anwendungen

Cerium(IV) oxide is used in ceramics, and to polish glass and stones. It is applied as a solid electrolyte in fuel cells. It can also be employed as a co-catalyst in a number of reactions. It is also used as an antioxidant and to generate hydrogen through water splitting. It is used as a high-temperature hydrocarbon oxidation catalyst in self-cleaning ovens. It can be used in infrared filters, incandescent mantles and sunscreens in combination with other materials. It finds use as a catalyst support and to sensitize photosensitive glass.

Bemerkungen

Reacts with strong acids or alkalies. Slightly hygroscopic. The powdered cerium dioxide can absorb small quantities of carbon dioxide from air.
