Gadolinium Oxide (Gd2O3) Product List

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 color TV tubes. 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 the 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.
