Cerium(IV) oxide, also known as ceric oxide, ceric dioxide, ceria, cerium oxide or cerium dioxide, is an oxide of the rare-earth metal cerium. It is a pale yellow-white powder with the chemical formula CeO 2. It is an important commercial product and an intermediate in the purification of the element from the ores.
Cerium(IV) oxide ("ceria") has the fluorite structure, similarly to the dioxides of praseodymium and terbium. Ceria is a nonstoichiometric compound, meaning that the real formula is CeO 2−x, where x is about 0.2. Thus, the material is not perfectly described as Ce(IV). Ceria reduces to cerium(III) oxide with hydrogen gas. [3]
Cerium(III) oxide, also known as cerium oxide, cerium trioxide, cerium sesquioxide, cerous oxide or dicerium trioxide, is an oxide of the rare-earth metal cerium. It has chemical formula Ce 2 O 3 and is gold-yellow in color. According to X-ray crystallography, the Ce(III) ions are seven-coordinate, a motif typical for other trivalent lanthanide ...

Cerium oxide may refer to: Cerium(III) oxide, Ce 2 O 3, also known as dicerium trioxide; Cerium(III, IV) oxide, Ce 3 O 4 (dark blue)
After the FDA has banned red dye No.3, you may be wondering which drinks and candies contain it. Here's the full list—plus, when it'll be removed from shelves.
A new study explains how mitochondria act as “reservoirs” to store NAD for cells to use, which could help scientists come up with NAD-boosting therapies to combat aging and age-related diseases.
Gadolinium-doped ceria (GDC) (known alternatively as gadolinia-doped ceria, gadolinium-doped cerium oxide (GCO), cerium-gadolinium oxide (CGO), or cerium(IV) oxide, gadolinium-doped, formula Gd:CeO 2) is a ceramic electrolyte used in solid oxide fuel cells (SOFCs).
