American Elements produces Bismuth Wafers with the highest possible density. Our standard wafer size is nominally 25.4 mm (1 inch) to 300 mm (11.8 inches). Materials are produced using crystallization, solid state and other ultra high purification processes such as sublimation. This process forms a cylindrical ingot which is then sliced and polished to form wafers. 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. We can also provide Pieces and Shot in smaller ranges. See research below.
We also produce Bismuth as disc, granules, ingot, pellets, pieces, powder, and rod . Other shapes are available by request.
Bismuth 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 it's 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 metals
such as tin, cadmium , etc., bismuth forms low-melting alloys which 
are 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 was first discovered by Early Man. The name Bismuth originates from the German word 'wissmuth' meaning white mass. See Bismuth research below.

Typical bulk packaging includes palletized plastic 5 gallon/25 kg. pails, fiber and steel drums to 1 ton super sacks in full container (FCL) or truck load (T/L) quantities. Research and sample quantities and hygroscopic, oxidizing or other air sensitive materials may be packaged under argon or vacuum. Shipping documentation includes a Certificate of Analysis and Material Safety Data Sheet (MSDS). Bullion and bar forms are best if purchasing solely for physical possession and risk exposure. |
