American Elements specializes in producing high purity Arsenic Circles with the highest possible densityHigh Purity (99.99%) Arsenic 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 nanoparticles. American Elements produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia) and follows applicable ASTM testing standards. Typical and custom packaging is available. See safety data and research below and pricing/lead time above. We also produce Arsenic as rod, pellets, powder, pieces, granules, ingot, and in compound forms, such as oxide. Other shapes are available by request.

Arsenic(As) atomic and molecular weight, atomic number and elemental symbolArsenic is a Block P, Group 15, Period 4 element. The number of electrons in each of Arsenic's shells is 2, 8, 18, 5 and its electronic configuration is [Ar] 3d10 4s2 4p3. In its elemental form arsenic's CAS number is 1327-53-3.Elemental Arsenic The arsenic atom has a radius of 124.5.pm and its Van der Waals radius is 185.pm. Though inorganic arsenic is extremely toxic, even in very small amounts, other forms of arsenic have proven safe and even potentially beneficial to humans: a study released in August 2012 by doctors at the Harbin Medical University Hospital in Harbin, China suggests that Arsenic Trioxide (As2O3) is an effective treatment for patients diagnosed with acute promyelocytic leukemia (APL). Arsenic has numerous applications as a semiconductor and other electronic applications as Indium arsenide, silicon arsenide and tin arsenide. Arsenic is finding increasing uses as a doping Arsenic Bohr Modelagent in solid-state devices such as transistors. Gallium arsenide is used as a laser material to convert electricity directly into coherent light. Arsenic is used in bronzing and for hardening and improving the sphericity of shot. Due to their toxicity, arsenic compounds are used in insecticides and wood preservation. Arsenic is available as metal and compounds with purities from 99% to 99.9999% (ACS grade to ultra-high purity); metals in the form of foil, sputtering target, and rod, and compounds as submicron and nanopowder. Arsenic is found in numerous minerals including arsenolite (As2O3), arsenopyrite (FeAsS), loellingite (FeAs2), orpiment (As2S3), and realgar (As4S4). Arsenic 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 Arsenic research below.
