About Selenium Microleaf

American Elements specializes in producing Selenium as rolled microfoils and sheets mounted on a removable support. Most foils are produced from cast ingots for use in coating and thin film Chemical Vapor Deposition (CVD) and Physical Vapor Deposition (PVD) processes including Ultra High Purity (99.9+%) Selenium MicroleafThermal and Electron Beam (E-Beam) Evaporation, Low Temperature Organic Evaporation, Atomic Layer Deposition (ALD), Organometallic and Chemical Vapor Deposition (MOCVD) for specific applications such as fuel cells and solar energy. Thickness can range from 0.003" to approximately 2mm for all metals. Some metals can also be rolled down as thin as 0.001" for use as an evaporation source in microelectronics, optics, magnetics, MEMS, and hard resistant coatings. Piece sizes are available up to approximately 7" maximum width. Maximum lengths of about 20" can be obtained with a nominal thickness between about 0.005" and 0.020" for thin film deposition on glass or metal substrates. 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. We also produce Selenium as rods, powder and plates. Other shapes are available by request.

Selenium Bohr ModelSee more Selenium products. Selenium (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 SeleniumOne of the most 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.
