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 CeO2. It is an important commercial product and an intermediate in the purification of the element from the ores. The distinctive property of this material is its reversible conversion to a non-stoichiometric oxide.
Further Applications
Polishing
The principal industrial application of ceria is for polishing, especially chemical-mechanical planarization (CMP). For this purpose, it has displaced many other oxides that were previously used, such as iron oxide and zirconia. For hobbyists, it is also known as "opticians' rouge".
Optics
CeO2 is used to decolorize glass by converting green-tinted ferrous impurities to nearly colorless ferric oxides.
Cerium oxide has found use in infrared filters, as an oxidizing species in catalytic converters and as a replacement for thorium dioxide in incandescent mantles.
Mixed conduction
Due to the significant ionic and electronic conduction of cerium oxide, it is well suited to be used as a mixed conductor, with significant value in fuel cell research and development.
Biomedical applications
Cerium oxide nanoparticles (nanoceria) have been investigated for their antibacterial and antioxidant activity.
Welding
Cerium oxide is used as an addition to Tungsten electrodes for Gas Tungsten Arc Welding. It provides advantages over pure Tungsten electrodes such as reducing electrode consumption rate and easier arc starting & stability.
Photocatalysis
While it 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 lower photocatalytic activity. However, its thermal catalytic properties have to be decreased by coating the particles with amorphous silica or boron nitride.
Fuel cells
Ceria is of interest as a material for solid oxide fuel cells (SOFCs) because of its relatively high oxygen ion conductivity (i.e. oxygen atoms readily move through it) at intermediate temperatures (500–650 °C) and lower association enthalpy compared to the Zirconia system.
Water splitting
The cerium(IV) oxide–cerium(III) oxide cycle or CeO2/Ce2O3 cycle is a two-step thermochemical water splitting process based on cerium(IV) oxide and cerium(III) oxide for hydrogen production.
Antioxidant
Nanoceria has attracted attention as a biological antioxidant.
