Gadolinium (Gd) Micron Metal Powder, Purity: 99.5%, Size: 325 mesh

$69.00

Gadolinium powder is relatively stable in dry air. It does however oxidize in moisture forming oxides.
It can be found in minerals such as xenotime, monazite and bastnaesite. Gadolinium is a rare earth
metal that possesses unique properties advantageous to specialized applications such as semiconductor
fabrication and nuclear reactor shielding. Gadolinium has excellent magnetic properties. It is weakly magnetic
at room temperature, but becomes strongly magnetic or ferromagnetic below room temperatures.

Gadolinium powder has applications in electronics to increase the speed and capacity of computer memory.
It has applications in medical magnetic resonance imaging (MRI) where it is used as intravenously administered,
contrasting agents to enhance images. It also has applications as a dopant in glass.

SKU: N/A Category: Tag:

Gadolinium powder 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. 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 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).
