Uses | Gadolinium oxide (Gd2O3) has multiple uses in medicine, chemical processes, electronics, and glass making. Gadolinium oxide is used in the creation of the phosphors used in television tubes as well as the creation of gadolinium yttrium garnets used in microwaves and materials used to absorb atomic reactions. Gadolinium has a shiny metallic lustre with a slight yellowish tint. It is both ductile and malleable. Gadolinium is utilized for both its high magnetic moment (7.94uB) and in phosphors and scintillated material. When mixed with EDTA dopants, it is used as an injectable contrast agent for patients undergoing magnetic resonance imaging. With its high magnetic moment, Gadolinium can reduce relaxation times and thereby enhance signal intensity. Gadolinium also possesses unusual metallurgic properties, with as little as 1% of Gadolinium improving the workability and resistance of Iron, Chromium, and related alloys to high temperatures and oxidation. Gadolinium compounds are also used for making green phosphors for color TV tubes. Gadolinium is used for making Gadolinium Yttrium Garnet (Gd:Y3Al5O12); it has microwave applications and is used in fabrication of various optical components and as substrate material for magneto-optical films. Gadolinium Metal is ferromagnetic, ductile and malleable metal, and widely used for making speciality alloys, MRI(magnetic Resonance Imaging), superconductive materials and magnetic refrigerator. Gadolinium is also used in nuclear marine propulsion systems as a burnable poison. In X-ray systems, gadolinium is contained in the phosphor layer, suspended in a polymer matrix at the detector. It is used for making Gadolinium Yttrium Garnet (Gd:Y3Al5O12); it has microwave applications and is used in fabrication of various optical components and as substrate material for magneto-optical films. 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). |
