See safety data below. American Elements specializes in producing Dysprosium High Purity Foil and sheets in many thicknesses and sizes for numerous industrial uses and provides health and occupational safety information for this product. Most foils are produced from cast ingots for use in coating and thin film Chemical Vapor Deposition (CVD) and Physical Vapor Deposition (PVD) processes including Ultra High Purity (99.9+%) thin film foilThermal and Electron Beam (E-Beam) Evaporation, Low Temperature Organic Evaporation, Atomic Layer Deposition (ALD), Organometallic and Chemical Vapor Deposition (MOCVD) for specific applications such as fuel cells and solar energy. Thickness can range from 0.003" to approximately 2mm for all metals. Some metals can also be rolled down as thin as 0.001" for use as an evaporation source in microelectronics, optics, magnetics, MEMS, and hard resistant coatings. Piece sizes are available up to approximately 7" maximum width. Maximum lengths of about 20" can be obtained with a nominal thickness between about 0.005" and 0.020" for thin film deposition on glass or metal substrates. Materials are produced using crystallization, solid state and other ultra high purification processes such as sublimation. American Elements specializes in producing custom compositions for commercial and research applications and for new proprietary technologies. American Elements also casts any of the rare earth metals and most other advanced materials into rod, bar, or plate form, as well as other machined shapes and through other processes such as nanoparticles and in the form of solutions and organometallics. We also produce Dysprosium as rods, powder and plates. Other shapes are available by request.



Packaging Specifications

Typical bulk packaging includes palletized plastic 5 gallon/25 kg. pails, fiber and steel drums to 1 ton super sacks in full container (FCL) or truck load (T/L) quantities. Research and sample quantities and hygroscopic, oxidizing or other air sensitive materials may be packaged under argon or vacuum. Shipping documentation includes a Certificate of Analysis and Safety Data Sheet (SDS). Solutions are packaged in polypropylene, plastic or glass jars up to palletized 440 gallon liquid totes, and 36,000 lb. tanker trucks.

Dysprosium Bohr ModelThe number of electrons in each of dysprosium's shells is [2, 8, 18, 28, 8, 2] and its electron configuration is [Xe] 4f10 6s2. The dysprosium atom has an atomic radius of 178 pm and a Van der Waals radius of 229 pm. Dysprosium was first discovered by Paul Emile Lecoq de Boisbaudran in 1886.In its elemental form, dysprosium has a silvery-white appearance. Elemental Dysprosium PictureIt is a member of the lanthanide or rare earth series of elements and, along with holmium, has the highest magnetic strength of all other elements on the periodic table, especially at low temperatures. Dysprosium is found in various minerals including bastnäsite, blomstrandine, euxenite, fergusonite, gadolinite, monazite, polycrase and xenotime. It is not found in nature as a free element. The element name originates from the Greek word dysprositos, meaning hard to get at.
