Gadolinium Oxide Powder (Gd2O3), CAS 12064-62-9
Gadolinium oxide powder (Gd2O3) is a white powder that is commonly used as a raw material for the production of other gadolinium compounds, such as gadolinium metal, gadolinium fluoride, and gadolinium nitrate.
Gadolinium oxide is insoluble in water, but soluble in acids. It has a high melting point of 2,425 °C and a high thermal conductivity, making it useful in high-temperature applications. It is also used as a neutron absorber in nuclear reactors, as a contrast agent in magnetic resonance imaging (MRI), and as a dopant in the production of solid-state lasers.
Gadolinium oxide powder should be stored in a cool, dry place, away from heat sources and incompatible materials. Proper protective equipment, such as gloves and safety goggles, should be worn when handling this material.

Specifications
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.
