Application
Gadolinium Oxide, also called Gadolinia, is used for making optical glass and Gadolinium Yttrium Garnets which have microwave applications. High purity of Gadolinium Oxide is used for making phosphors for colour TV tube. Cerium Oxide (in the form of Gadolinium doped ceria) creates an electrolyte with both high ionic conductivity and low operating temperatures that are optimal for cost-effective production of fuel cells. It is one of the most commonly available forms of the rare earth element Gadolinium, derivatives of which are potential contrast agents for magnetic resonance imaging.
Gadolinium Oxide is used for making gadolinium metal, gadolinium iron alloy, memory memory single substrate, optical glass, solid magnetic refrigerant, inhibitor, samarium cobalt magnet additive, x-ray intensifying screen, magnetic refrigerant, etc.
In the glass industry, gadolinium oxide is specifically used as a component of high refractive index glass. When used together with lanthanum, gadolinium oxide helps to change the glass transition zone and improve the thermal stability of the glass. The nuclear industry is used for control rods of nuclear reactors, neutron absorbing materials in atomic reactors, magnetic bubble materials, intensifying screen materials, etc. Gadolinium oxide can also be used to manufacture capacitors, X-ray intensifying screens, and gadolinium gallium garnet materials.
