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.

Selenide(Se) atomic and molecular weight, atomic number and elemental symbolSelenium is a Block P, Group 16, Period 4 element. The number of electrons in each of Selenium's shells is 2, 8, 18, 6 and its electronic configuration is [Ar] 3d10 4s2 4p4. In its elemental form selenium's CAS number is 7782-49-2. The selenium atom has a radius of 116.pm and its Van der Waals radius is 190.pm. The EPA does not classify selenium as carcinogenic, although selenium sulfide Elemental Seleniumis a probable carcinogen. Selenates and selenites which are compounds of selenium, are highly toxic. Hydrogen selenide gas (SeH2) is the most acutely toxic compound of selenium. Selenium exhibits both photovoltaic action, where light is converted directly into electricity, and photoconductive action, where the electrical resistance decreases with increased illumination. of photocells and exposure meters for photographic use, as Selenium Bohr Modelwell as solar cells. Below its melting point, selenium is a p-type semiconductor and has many uses in electronic and solid-state applications. In 2013, University of Notre Dame scientists created a unique type of solar cell by layering quantum dots of selenium, cadmium, and sulfur; the tandem-layered quantum dot cell exhibited a synergistic efficiency higher than the combined efficiencies of multiple single-layered cells. Selenium 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. Selenium, first discovered by Jons Berzelius in 1817, is produced from selenide which is found in many sulfide ores. The origin of the name Selenium comes from the Greek word "Selênê" meaning moon. See selenium research below.
