American Elements specializes in supplying seamless Selenium tubing with a variety of dimensions including round, rectangular, square, and
oval 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. Materials 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 is a Block P, Group 16, Period 4 element. The 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 it's Van der Waals radius is 190.pm. Selenium exhibits both photovoltaic action, where light is converted directly into electricity, and photoconductive action, where the electrical resistance decreases with increased illumination. These properties make selenium useful in the production of photocells and exposure meters for photographic use, as well as solar cells. Below its melting point, selenium is a p-type semiconductor and has many uses in electronic and solid-state applications. |
