What is Cerium Oxide Polish?

Cerium oxide, sometimes spelled ceric oxide, ceric dioxide, ceria, cerium oxide, or cerium dioxide, is a rare-earth metal oxide. It is a powder that is light yellow-white and has the chemical formula CeO2. 

It is a significant commercial product and a necessary intermediary in the process of extracting the element from its ores. This material is distinguished by its reversible conversion to a non-stoichiometric oxide.

The application of Cerium Oxide Polish Compound is, that it is used to polish glass and mirror surfaces and remove small scratches and scuff marks. 

Remove scratches and scuff marks from glass and mirrors with Cerium Oxide and a Felt Polishing Wheel. 

Combine with water to form a paste to make a scratch remover that works quickly.

Occurrence in nature

Cerium oxide is a naturally occurring mineral in the form of cerianite (Ce). It is a very unusual occurrence of a tetravalent cerium mineral; the other two are stetindite-(Ce) and dyrnaesite-(Ce) (La). 

The suffix “-(Ce)” is referred to as a Levinson modifier and is used to indicate which element dominates a certain structural location. It often appears in the names of minerals containing rare earth elements (REEs). 

Cerianite-(Ce) is associated with many instances of cerium anomaly, in which Ce, is readily oxidized and is isolated from other REEs that stay trivalent and hence conform to the structures of minerals other than cerianite- (Ce).


Cerium occurs naturally in combination with other rare-earth elements in two of its primary ores, bastnaesite, and monazite. Following the extraction of metal ions into an aqueous base, Ce is removed from the mixture using an oxidant followed by pH correction. 

This procedure makes use of CeO2’s limited solubility and the fact that other rare-earth elements are resistant to oxidation.

Cerium oxide is generated when cerium oxalate or cerium hydroxide is calcinated.

Cerium also produces cerium oxide, Ce2O3, which is a highly reactive compound that will oxidize to cerium oxide.

Applications of Cerium Oxide 

  1. Polishing

Cerium Oxide is mostly used in industry for polishing, particularly chemical-mechanical planarization (CMP). It has largely superseded several other oxides formerly used for this purpose, including iron oxide and zirconia. It is also referred to as “opticians’ rouge” by enthusiasts.

  1. Optics

By converting green-tinted ferrous impurities to almost colorless ferric oxides, CeO2 is used to decolorize glass.

Cerium oxide is used in infrared filters, catalytic converters, and as a substitute for thorium dioxide in incandescent mantles.

  1. Mixed conduction

Due to cerium oxide’s high ionic and electronic conductivity, it is an excellent candidate for use as a mixed conductor, which has substantial importance in fuel cell research and development.

  1. Applications in biomedicine

The antibacterial and antioxidant activity of cerium oxide nanoparticles (nanoceria) has been explored.

  1. Welding

Cerium oxide is added to tungsten electrodes during the gas tungsten arc welding process. It has several benefits over pure Tungsten electrodes, including a lower rate of electrode consumption and simpler arc onset and stability. 

Ceria electrodes were introduced to the US market in 1987 and are used in a variety of applications including AC, DC Electrode Positive, and DC Electrode Negative.

Bottom Line 

So these are all about the Cerium Oxide polish and its applications.
