Niobium Bromide is a highly water soluble crystalline Niobium source for uses compatible with Bromides and lower (acidic) pH. Metallic Bromides are marketed under the trade name AE Bromides™. Most metal bromide compounds are water soluble for uses in water treatment, chemical analysis and in ultra high purity for certain crystal growth applications. Bromide in an aqueous solution can be detected by adding carbon disulfide (CS2) and chlorine. Niobium Bromide is generally immediately available in most volumes. Ultra high purity and high purity compositions improve both optical quality and usefulness as scientific standards. Nanoscale (See also Nanotechnology Information and Quantum Dots) elemental powders and suspensions, as alternative high surface area forms, may be considered.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. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.
Niobium 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 it's 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 and small advanced electronics, such as cell phones, pagers and laptop computers. Niobium 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. Niobium has medical research applications. It is alloyed to produce arc-welding rods and in corrosion-resistant steel. 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.
