American Elements specializes in producing high purity uniform shaped Silicon Slugs with the highest possible density High Purity Slugsand 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 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.

The number of electrons in each of Silicon's shells is 2, 8, 4 and its electron configuration is [Ne] 3s2 3p2. The silicon atom has a radius of 111 pm and a Van der Waals radius of 210 pm. Silicon was discovered and first isolated by Jöns Jacob Berzelius in 1823. Silicon makes up 25.7% of the earth's crust, by weight, and is the second most abundant element, exceeded only by oxygen. The metalloid is rarely found in pure crystal form and is usually produced from the iron-silicon alloy ferrosilicon. Silica (or silicon dioxide), as sand, is a principal ingredient of glass, one of the most inexpensive of materials with excellent mechanical, optical, thermal, and electrical properties. 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 industry.The name Silicon originates from the Latin word silex which means flint or hard stone.

Free Test Sample Program

We recognize many of our customers are purchasing small quantities directly online as trial samples in anticipation of placing a larger future order or multiple orders as a raw material for production. Since our primary business is the production of industrial quantities and/or highly consistent batches which can be used for commercial production and purchased repeatedly in smaller quantity, American Elements offers trial samples at no charge on the following basis. Within 6 months of purchasing materials directly online from us, you have the option to refer back to that order and advise that it is the intention of your company, institution or lab to either purchase a larger quantity, purchase the material in regular intervals or purchase more on some other basis.

We will then evaluate your future needs and assuming the quantity or number of future purchases qualify, we will fully credit your purchase price with the next order. Because of the many variables in the quantity and number of orders you may place, it is impossible to evaluate whether your future order(s) will qualify for this program prior to your placing your next order. Please know American Elements strongly desires to make this free sample program available to you and will make every effort to do so once your next order is placed.
