Gadolinium, atomic no.: 64, symbol as Gd, weight at 157.25, 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. |
