About Gadolinium Metal

High Purity (99.999%) Gadolinium (Gd) MetalGadolinium Metal is available as disc, granules, ingot, pellets, pieces, powder , rod, wire, and sputtering target. American Elements produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia) and follows applicable ASTM testing standards. Typical and custom packaging is available. Ultra high purity and high purity forms also include metal powder, submicron powder and nanoscale, quantum dots, targets for thin film deposition, pellets for evaporation and single crystal or polycrystalline forms. Elements can also be introduced into alloys or other systems as fluorides, oxides or chlorides or as solutions. Gadolinium metal is generally immediately available in most volumes. Gadolinium is utilized for both its high magnetic moment (7.94 µB) and in phosphors and scintillators. When complexed with EDTA ligands, it is used as an injectable contrast agent for patients undergoing magnetic resonance imaging.
