Description and Uses

Gadolinium(III) oxide is used as a raw material for various fluorescent compounds, absorption material in atomic reactions, nuclear fuels, magnetic bubble material and screen-sensitivity increasing material. It is also used in glass and electronic industries. It also acts as a neutron shield, a catalyst, a dielectric ceramic and is used for filament coatings, special glasses, lasers, masers and telecommunication. It also serves as a laboratory reagent. It plays an important role as a potential contrast agent for magnetic resonance imaging (MRI).
