Property: 
Good redox property. 
Small particle size, and mono crystal structure, 
Good capability of storaging and releasing oxygen. 
Very good catalyst and polishing agent. 
Better polishing property than normal zirconia. 


Application: 
Glass and Ceramics :
Cerium oxide is used to polish glass surfaces, having largely replaced jewellers rouge in the glass industry. Cerium compounds are also used in the manufacture of glass and enamels, both as a component and as a decolouriser. Cerium in combination with titanium gives glass a golden yellow colour. Cerium oxide (Ce2O3 and CeO2) is also a component of the walls of self-cleaning ovens
 
In LED's:
Cerium combined with yttrium turns blue light into white light. Cerium oxide, in combination with tin oxide (SnO) is used for UV absorption for solar panels. Cerium is also used to stabilize zirconia and for alumina ceramics in catalytic converters. It is also utilized in dental ceramics
 
Alloys and Metals:
Cerium is alloyed with iron to make nodular iron to improve machineability of automotive power-train components
 
Catalysts:
Cerium oxide is used as a catalytic converter to reduce carbon monoxide emissions in the exhaust gases from motor vehicles. Cerium additives to diesel fuel enable the fuel to burn more cleanly, with less resulting air-pollution.
