American Elements specializes in producing high purity Gold Granules with the highest possible density and smallest possible average grain sizes for use in Chemical Vapor Deposition (CVD) and Physical Vapor Deposition (PVD) processes including Thermal and Electron Beam (E-Beam) Evaporation, Low Temperature Organic Evaporation, Atomic Layer Deposition (ALD), Metallic-Organic and Chemical Vapor Deposition (MOCVD). Our standard Granules are amorphous uniform pieces in sizes ranging from < 1 mm, 1-2 mm, and 3-5 mm. 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 research below. We also produce Gold as rod, pellets, powder, pieces, disc, ingot, wire, and in compound forms, such as oxide. Other shapes are available by request.

Gold is a Block D, Group 11, Period 6 element. The electronic configuration is [Xe] 4f142 5d10 6s1. In its elemental form gold's CAS number is 7440-57-5. The gold atom has a radius of 144.2.pm and it's Van der Waals radius is 166.pm. Gold is a soft metal and is usually alloyed to give it more strength. It is a good conductor of heat and electricity, and is unaffected by air and most reagents. It is used in coinage and is a standard for monetary systems. It is also extensively used for jewelry, dental work, and for plating.
