Cerium oxide is used as a catalytic converter for the minimisation of CO emissions in the exhaust gases from motor vehicles. Cerium (Ce) is a member of the lanthanide series of metals on the periodic table. [citation needed], Ceria is of interest as a material for solid oxide fuel cells (SOFCs) because of its relatively high oxygen ion conductivity (i.e. About 6% of these are rare earth & products, 1% are oxide, and 1% are other chemicals. oxygen atoms readily move through it) at intermediate temperatures (500–650 °C) and lower association enthalpy compared to Zirconia system. [13][14] It is a rare example of tetravalent cerium mineral, the other examples being stetindite-(Ce) and dyrnaesite-(La). Cerium oxide. Defects and Defect Processes in Nonmetallic Solids By William Hayes, A. M. Stoneham Courier Dover Publications, 2004. This step exploits the low solubility of CeO2 and the fact that other rare-earth elements resist oxidation.[2]. It is a pale yellow-white powder with the chemical formula CeO2. It is a suspension treated cerium, so it should stay in solution quite readily when mixed with water and require less cerium to accomplish a polish in a short amount of time. American Elements manufactures oxide nanopowders and nanoparticles with typical particle sizes ranging from 10 to 200nm and in coated and surface functionalized forms. The primary defects of concern are oxygen vacancies and small polarons (electrons localized on cerium cations). These factors give ceria favorable performance in applications as a solid electrolyte in solid-oxide fuel cells. In the most stable fluorite phase of ceria, it exhibits several defects depending on partial pressure of oxygen or stress state of the material.[8][9][10][11]. According to theory, cerium oxide shows a UV cut-off threshold at around 370 nm, similar to that of nano titanium oxide. Hydrophobicity tends to impart resistance to water-deactivation at the surfaces of catalysts and thus enhances the adsorption of organic compounds. Samples produced in this way are only slowly air-oxidized back to the dioxide at room temperature. A wide variety of cerium oxide red color options are available to you, such as rare earth oxide, rare earth powder.
