Oxide IonAmerican Elements specializes in producing high purity uniform shaped Niobium Oxide Pellets 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 Pellet sizes range from 1/8" x 1/8" to 1/4" x 1/4" and 3 mm diameter. We can also provide Pellets 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 such as nanoparticles (See also application discussion at Nanotechnology Information and at Quantum Dots) and in the form of solutions and organometallics. We also produce Niobium Oxide as pieces, tablets, powder, and sputtering target. Oxide compounds are not conductive to electricity. However, certain perovskite structured oxides are electronically conductive finding application in the cathode of solid oxide fuel cells and oxygen generation systems. American Elements produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia) and follows applicable ASTM testing standards. Typical and custom packaging is available. See safety data and research below and pricing/lead time above. Other shapes are available by request.

Niobium(Nb) atomic and molecular weight, atomic number and elemental symbolNiobium is a Block D, Group 5, Period 5 element. The number of electrons in each of Niobium's shells is 2, 8, 18, 12, 1 and its electronic configuration is [Kr] 4d4 5s1. In its elemental form niobium's CAS number is 7440-03-1. The niobium atom has a radius of 142.9.pm and its Van der Waals radius is 200.pm. Some niobium compounds are considered very toxic. Niobium is the basis for various barium titanate compositions used as dielectric coatings in telecommunications Niobium Bohr Modeland small advanced electronics, such as cell phones, pagers and laptop computers. Caltech and JPL researchers recently developed a new type of electrical signal boosting amplifier made from a niobium titanium nitride superconducting material. The device has a variety of potential applications ranging from studying stars, galaxies, and black holes to exploring the quantum world and developing quantum computers. Niobium is available as metal Elemental Niobium 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. Niobium has medical research applications. It is alloyed to produce arc-welding rods and in corrosion-resistant steel. Niobium is not found in nature as a free element, but it does occur in minerals. Niobium was first discovered by Charles Hatchett in 1801. The word Niobium originates from Niobe, daughter of mythical Greek king Tantalus. See Niobium research below.
