American Elements specializes in producing high purity Palladium Lump with the highest possible density and smallest possible average grain sizes for use in Chemical Vapor Deposition (CVD) and Physical Vapor Deposition (PVD) processes including Thermal and Electron Beam (E-Beam) Evaporation, Low Temperature Organic Evaporation, Atomic Layer Deposition (ALD), Metallic-Organic and Chemical Vapor Deposition (MOCVD). Our standard lump pieces are amorphous uniform pieces in sizes ranging from 5-15 mm. Lump 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 granules, rod, bar or plate form, as well as other machined shapes and through other processes such as nanoparticles (See also application discussion at Nanotechnology Information and at Quantum Dots) and in the form of solutions and organometallics. See safety data and research below and pricing/lead time above. We also produce Palladium as rod, pellets, powder, pieces, disc, ingot, wire, and in compound forms, such as oxide. Other shapes are available by request.
Palladium is a Block D, Group 10, Period 5 element. The number of electrons in each of Palladium's shells is 2, 8, 18, 18 and its electronic configuration is [Kr] 4d10. In its elemental form palladium's CAS number is 7440-05-3. The palladium atom has a radius of 137.6.pm and it's Van der Waals radius is 163.pm. Palladium is a member of the platinum group of metals. It is an excellent hydrogenation and dehydrogenation catalyst and available in many Organo-metallic forms for this purpose. It is alloyed with gold, silver, iridium and other platinum group elements and used in jewelry. The metal is used in dentistry, watch making, and in making surgical instruments and electrical contacts. Platinum is available as metal and compounds with purities from 99% to 99.999% (ACS grade to ultra-high purity); metals in the form of foil, sputtering target, and rod, and compounds as submicron and nanopowder. Palladium was first discovered by William Hyde Wollaston in 1803. See Palladium research below.
PACKAGING SPECIFICATIONS FOR BULK & RESEARCH QUANTITIES
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 Material Safety Data Sheet (MSDS). Bullion and bar forms are best if purchasing solely for physical possession and risk exposure.
