The glass is initially colored by the metal contaminates present in the raw materials used to produce glass. Iron oxide is a moderately strong colorant in glass and as little as0.01 % can be visually detected. The ferrous component present in it provides a blue-greenish tinge with nearly ten times as strong a discoloring power as the brown-yellow of the ferric ion. Cerium oxidizes these metals and eliminates unwanted color
It absorbs ultraviolet radiation strongly. Because of cerium, TV screens remain clear and visible even after long use.
Opacifier in Enamels:
Cerium oxide has a high refractive index and is a potential opacifying agent in enamel compositions used as protective coatings on metals.
Thermochemical water splitting process based on Cerium (IV) oxide and Cerium (III) oxide for hydrogen production.
Thermoelectric material, cerium tungsten electrodes, cerium silicon carbide abrasive, In solid oxide fuel cells because of its relatively high oxygen ion conductivity, some permanent magnetic materials, all kinds of alloy steel and non-ferrous metals, medicines.
