Products

Gadolinium Metal is a ferromagnetic, ductile, and malleable metal, and is widely used for making specialty alloys, MRI (Magnetic Resonance Imaging), superconductive materials, and magnetic refrigerators. Gadolinium is also used in nuclear marine propulsion systems as a burnable poison. Gadolinium as a phosphor is also used in other imaging. 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 the 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).

Application

  • Gadolinium is a metal or a salt that absorbs neutrons and is, therefore, used sometimes for shielding in neutron radiography and in nuclear reactors.
  • Like most rare earth, gadolinium forms trivalent ions with fluorescent properties, and salts of gadolinium(III) are used as phosphors in various applications.
