Barium Chunk
American Elements specializes in producing high purity Barium Chunk 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 Chunk pieces are amorphous uniform pieces in sizes ranging from 5-15 mm. Chunk 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 research below. We also produce Barium as rod, pellets, powder, pieces, disc, ingot, wire, and in compound forms, such as oxide. Other shapes are available by request.
Barium is a Block S, Group 2, Period 6 element. The number of electrons in each of Barium's shells is 2, 8, 18, 18, 8, 2 and its electronic configuration is [Xe] 6s2. In its elemental form barium's CAS number is 7440-39-3. The barium atom has a radius of 217.4.pm and it's Van der Waals radius is 200.pm. Barium powder can ignite spontaneously in air and when Barium compounds are water or acid soluble, they are very poisonous. Barium sulfate which is used in x-ray imaging, is highly insoluble in water, and consequently completely removed from the digestive tract. Barium is a member of the alkaline-earth metals. It has technical applications in glass, electronics and medicine. It is also used in paints and colorants. Electronic coatings based on barium titanate are essential to cell phones and other microelectronics. It has long been used in medical diagnostic techniques because it makes a good x-ray contrast medium. Barium is a dopant in various fluorescent lamp coating formulas. Barium information, including Technical Data, Safety Data and its High Purity properties , research , applications and other useful facts are discussed here. Scientific facts such as the atomic structure, ionization energy , abundance on Earth , conductivity and thermal properties are included. See Barium 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.
