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 Bohr ModelArsenic (As) atomic and molecular weight, atomic number and elemental symbolArsenic (atomic symbol: As, atomic number: 33) is a Block P, Group 15, Period 4 element with an atomic radius of 74.92160. The number of electrons in each of arsenic's shells is 2, 8, 18, 5 and its electron configuration is [Ar] 3d10 4s2 4p3. The arsenic atom has a radius of 119 pm and a Van der Waals radius of 185 pm. Arsenic was discovered in the early Bronze Age, circa 2500 BC. It was first isolated by Albertus Magnus in 1250 AD. In its elemental form, arsenic is a metallic grey, brittle, crystalline, semimetallic solid.Elemental Arsenic Arsenic is found in numerous minerals including arsenolite (As2O3), arsenopyrite (FeAsS), loellingite (FeAs2), orpiment (As2S3), and realgar (As4S4). 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 agent in solid-state devices such as transistors.
