American Elements specializes in producing high purity uniform shaped Tantalum Rod with the highest possible density 99.9+% Ultra High Purity Metallic Rods 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 safety data and research below and pricing/lead time above. We also produce Tantalum as powder, ingot, pieces, pellets, disc, granules, wire, and in compound forms, such as oxide. Other shapes are available by request.

Tantalum (Ta) atomic and molecular weight, atomic number and elemental symbolTantalum (atomic symbol: Ta, atomic number: 73) is a Block D, Group 5, Period 6 element with an atomic weight of 180.94788. The number of electrons in each of tantalum's shells is [2, 8, 18, 32, 11, 2] and its electron configuration is [Xe] 4f14 5d3 6s2. Tantalum Bohr ModelThe tantalum atom has a radius of 146 pm and a Van der Waals radius of 217 pm Tantalum was first discovered by Anders G. Ekeberg in 1802 in Uppsala, Sweden; however, it was not until 1844 when Heinrich Rose first recognized it as a distinct element. High Purity (99.999%) Tantalum (Ta) Metal In its elemental form, tantalum has a grayish blue appearance. Tantalum is found in the minerals tantalite, microlite, wodginite, euxenite, and polycrase. Due to the close relation of tantalum to niobium in the periodic table, Tantalum's name originates from the Greek word Tantalos meaning Father of Niobe in Greek mythology.
