American Elements specializes in producing high purity uniform shaped Rhenium Rod with the highest possible density and 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 Rod sizes range from 1/8" x 1/8" to 1/4" x 1/4" and 3 mm diameter. We can also provide Rod outside this range and deposition materials for specific applications such as fuel cells and solar energy and 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 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 (See also application discussion at Nanotechnology Information and at Quantum Dots) and in the form of solutions and organometallics. We have a variety of standard sized rod molds.. See research below. We also produce Rhenium as powder, ingot, pieces, pellets, disc, granules, wire, and in compound forms, such as oxide. Other shapes are available by request.
Rhenium is a Block D, Group 7, Period 6 element. The electronic configuration is [Xe] 4f14 5d5 6s2. In its elemental form rhenium's CAS number is 7440-15-5. The rhenium atom has a radius of 137.1.pm and it's Van der Waals radius is 200.pm. Rhenium is the fourth densest element exceeded only by that of platinum, iridium, and osmium . It has the second highest melting point exceeded only by tungsten and carbon . Rhenium is available as metal and compounds with purities from 99% to 99.999% (ACS grade to ultra-high purity); metals in the form of foil, sputtering target, and rod, and compounds as submicron and nanopowder. Because of this, thermocouples made of Tungsten/Rhenium alloy is are used when temperatures will rise to 2000 C and rhenium wire is used in photoflash lamps for photography. It is widely used as filaments for mass spectrographs and ion gauges.
