American Elements specializes in producing high purity uniform shaped Silicon Slugs with the highest possible density and smallest possible average grain sizes for use in semiconductor, 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 Slug sizes range from 1/8" x 1/8" to 1/4" x 1/4" and 3 mm diameter. We can also provide Slugs outside this range for ultra high purity thin film applications, such as fuel cells and solar energy layers. 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 safety data and research below and pricing/lead time above. We also produce Silicon as rod, ingot, powder, pieces, disc, granules, wire, and in compound forms, such as oxide. Other shapes are available by request.
Silicon is a Block P, Group 14, Period 3 element. The number of electrons in each of Silicon's shells is 2, 8, 4 and its electronic configuration is [Ne] 3s2 3p2. In its elemental form silicon's CAS number is 7440-21-3. The silicon atom has a radius of 117.6.pm and its Van der Waals radius is 210.pm. Silicon is not toxic but can cause chronic respiratory problems if inhaled as a fine silica or silicate dust. Asbestos silicates are carcinogenic. Silicon is makes up 25.7% of the earth's crust, by weight, and is the second most abundant element, exceeded only by oxygen. The Czochralski process is commonly used to produce single crystals of silicon used for solid-state or semiconductor devices. Silica, as sand, is a principal ingredient of glass, one of the most inexpensive of materials with excellent mechanical, optical, thermal, and electrical properties. Silicon 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. Ultra high purity silicon can be doped with boron, gallium, phosphorus , or arsenic to produce silicon for use in transistors, solar cells, rectifiers, and other solid-state devices which are used extensively in the electronics and space-age industries. Hydrogenated amorphous silicon has shown promise in producing economical cells for converting solar energy into electricity; in 2013, silicon nanoparticles created by scientists at the University of Buffalo successfully demonstrated the release of hydrogen, furthering the advancement of green energy technologies. Silcones are important products of silicon. They range from liquids to hard, glasslike solids with many useful properties. Silicon, first discovered by Jons Berzelius in 1823, is rarely found in pure crystal form and is usually produced from the iron-silicon alloy Ferrosilicon. The name Silicon originates from the Latin word "silex" which means flint or hard stone. See Silicon research below.
