American Elements specializes in producing high purity uniform shaped Selenium 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 nanoparticles. See research below. We also produce Selenium as rod, ingot, powder, pieces, disc, granules, wire, and in compound forms, such as oxide. Other shapes are available by request.

Selenium Bohr ModelSelenide(Se) atomic and molecular weight, atomic number and elemental symbolSelenium (atomic symbol: Se, atomic number: 34) is a Block P, Group 16, Period 4 element with an atomic radius of 78.96. The number of electrons in each of Selenium's shells is 2, 8, 18, 6 and its electron configuration is [Ar] 3d10 4s2 4p4. The selenium atom has a radius of 120 pm and a Van der Waals radius of 190 pm. Selenium is a non-metal with several allotropes: a black, vitreous form with an irregular crystal structure; three red-colored forms with monoclinic crystal structures; and a gray form with a hexagonal crystal structure, the most stable and dense form of the element. Elemental Selenium One of the mose common uses for selenium is in glass production; the red tint that it lends to glass neutralizes green or yellow tints from impurities in the glass materials. Selenium was discovered and first isolated by Jöns Jakob Berzelius and Johann Gottlieb Gahn in 1817. The origin of the name Selenium comes from the Greek word "Selênê," meaning moon.
