American Elements specializes in supplying seamless Selenium tubing with a variety of dimensions including round, rectangular, square, and Round Metallic Tubes--Selected Dimensionsoval in numerous standard diameters from 0.02 to 6.0 inches and wall thicknesses from 0.003 to 0.500 inches.Tubing can be further processed to produce rings, washers, sleeves and sheaths. Custom configurations are also available. Selected Ultra High Purity Metallic TubesMaterials include most metals including the rare earth metals and other advanced materials. Tubes can also be produced from custom materials and alloys for commercial and research applications and for new proprietary technologies. Other available shapes include bar or plate form, as well as custom 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 research below. We also produce Selenium as rod, pellets, powder, pieces, granules, ingot, 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.
