merican Elements specializes in producing high purity Bismuth 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. 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 Bismuth as rod, pellets, powder, pieces, granules, ingot, wire, and in compound forms, such as oxide. Other shapes are available by request.

Bismuth(Bi) atomic and molecular weight, atomic number and elemental symbolBismuth is a Block P, Group 15, Period 6 element. The number of electrons in each of Bismuth's shells is 2, 8, 18, 32, 18, 5 and its electronic configuration is [Xe] 4f14 5d10 6s2 6p3. In its elemental form bismuth's CAS number is 7440-69-9. The bismuth atom has a radius of 154.5.pm and its Van der Waals radius is 200.pm. Bismuth is not toxic. Bismuth is the most diamagnetic of all metals, and the thermal conductivity is lower than any metal, except mercury. Bismuth is not toxic. It has a high electrical resistance, and has the highest Hall Effect of any metal (i.e., greatest increase in electrical resistance when placed in a magnetic field). Bismuth expands on solidification. This property makes bismuth alloys particularly suited to the making of sharp castings of objects subject to damage by high temperatures. With other metalsElemental Bismuth such as tin, cadmium , etc., bismuth forms low-melting alloys which Bismuth Bohr Modelare extensively used for safety devices in fire detection and extinguishing systems. Bismuth is used in producing malleable irons and is finding use as a catalyst for making acrylic fibers. When bismuth is heated in air it burns with a blue flame, forming yellow fumes of the oxide. The metal is also used as a thermocoupling material, and has found application as a carrier for 235 U or 233 U fuel in nuclear reactors. Its soluble salts are characterized by forming unsoluble basic salts on the addition of water, a property sometimes used in detection work. Bismuth oxychloride is used extensively in cosmetics. Bismuth is found in bismuthinite Bi2S3 and bismite Bi2O3. It is also produced as a byproduct of lead, copper, tin, molybdenum and tungsten extraction. Bismuth was first discovered by Early Man. The name Bismuth originates from the German word 'wissmuth' meaning white mass. See Bismuth research below.
