Gadolinium Hydroxide all called Gadolinium Hydrate, is used for making laser crystal and dopant for Gadolinium Yttrium Garnets which have microwave applications. Gadolinium Hydroxide 99.999% is also used for making green phosphors for color TV tubes. It is used in many quality assurance applications, such as line sources and calibration phantoms. Gadolinium Gallium Garnet (GGG, Gd3Ga5O12) was used for imitation diamonds and for computer bubble memory. It can also serve as an electrolyte in Solid Oxide Fuel Cells (SOFCs).
