American Elements specializes in producing high purity Barium Circles with the highest possible densityHigh Purity (99.99%) Metallic Circleand smallest possible average grain sizes for use in semiconductor, chemical vapor deposition (CVD) and physical vapor deposition (PVD) display and optical applications. Our standard Circle sizes range from 1" to 8" in diameter and from 2mm to 1/2" thick. We can also provide Circles outside this range. 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 (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 Barium as rod, pellets, powder, pieces, granules, ingot, wire, and in compound forms, such as oxide. Other shapes are available by request.

Barium(Ba) and molecular weight, atomic number and elemental symbolBarium 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 its 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, used in x-ray imaging, is highly insoluble in water, and consequently can be completely removed from the digestive tract. Barium is a member of the Elemental Barium alkaline-earth metals. It has technical applications in glass, electronics and medicine. It is also Barium Bohr Modelused 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. The main commercial source of barium is barite, BaSO4. 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.
