Ultra High Purity Metal PowdersAmerican Elements specializes in producing high purity Niobium Powder with the smallest possible average grain sizes for use in preparation of pressed and bonded sputtering targets and in 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). Powders are also useful in any application where high surface areas are desired such as water treatment and in fuel cell and solar applications. Nanoparticles also produce very high surface areas. Our standard Powder particle sizes average in the range of - 325 mesh, - 100 mesh, 10-50 microns and submicron (< 1 micron). We can also provide many materials in the nanoscale range. 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. We also produce Niobium as rod, ingot, pieces, pellets, disc, granules, wire, and in compound forms, such as oxide. Other shapes are available by request.

Niobium Bohr ModelThe number of electrons in each of niobium's shells is 2, 8, 18, 12, 1 and its electron configuration is [Kr] 4d4 5s1. The niobium atom has a radius of 146 pm and a Van der Waals radius of 207 pm. Niobium was discovered by Charles Hatchett in 1801 and first isolated by Christian Wilhelm Blomstrand in 1864. Elemental NiobiumIn its elemental form, niobium has a gray metallic appearance. Niobium has the largest magnetic penetration depth of any element and is one of three elemental type-II superconductors (along with vanadium and technetium). Niobium is found in the minerals pyrochlore, its main commercial source, and columbite. The word Niobium originates from Niobe, daughter of mythical Greek king Tantalus.

Free Test Sample Program

We recognize many of our customers are purchasing small quantities directly online as trial samples in anticipation of placing a larger future order or multiple orders as a raw material for production. Since our primary business is the production of industrial quantities and/or highly consistent batches which can be used for commercial production and purchased repeatedly in smaller quantity, American Elements offers trial samples at no charge on the following basis. Within 6 months of purchasing materials directly online from us, you have the option to refer back to that order and advise that it is the intention of your company, institution or lab to either purchase a larger quantity, purchase the material in regular intervals or purchase more on some other basis.

We will then evaluate your future needs and assuming the quantity or number of future purchases qualify, we will fully credit your purchase price with the next order. Because of the many variables in the quantity and number of orders you may place, it is impossible to evaluate whether your future order(s) will qualify for this program prior to your placing your next order. Please know American Elements strongly desires to make this free sample program available to you and will make every effort to do so once your next order is placed.
