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 (atomic symbol: Ba, atomic number: 56) is a Block S, Group 2, Period 6 element with an atomic weight of 137.27. The number of electrons in each of barium's shells is [2, 8, 18, 18, 8, 2] and its electron configuration is [Xe] 6s2. Barium Bohr ModelBarium is a member of the alkaline-earth metals. The barium atom has a radius of 222 pm and a Van der Waals radius of 268 pm. Barium was discovered by Carl Wilhelm Scheele in 1772 and first isolated by Humphry Davy in 1808. Elemental Barium In its elemental form, barium is a soft, silvery-gray metal. Industrial applications for barium include acting as a "getterer," or unwanted gas remover, for vacuum tubes, and as an additive to steel and cast iron. Barium is also alloyed with silicon and aluminum as load-bearing alloys. The main commercial source of barium is the mineral barite (BaSO4); it does not occur naturally as a free element . The name barium is derived from the Greek word "barys," meaning heavy.
