Gadolinium oxide is used as a component of high refractive index glass in glass industry. Gadolinium oxide is used with lanthanum, which helps to change the glass transition area and improve the thermal stability of glass. Nuclear industry is used in nuclear reactor control rods, neutron absorption materials in atomic reactor, magnetic bubble materials, sensitizing screen materials and so on. Gadolinium oxide can also be used to manufacture capacitors, X-ray sensitizing screens and Gadolinium Garnet materials.
