niobium pentoxide with high quality

 About Niobium

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 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.

  Niobium, also termed Columbium, is a shiny grey metal that  takes on a bluish tinge when exposed to air at room temperature. Due to its low  capture cross section for thermal neutrons, Niobium has application in the  nuclear industry. Niobium can be electrically heated and anodized to a wide  variety of colors that makes it very attractive in the jewelry industry.  Niobium is added to iron or nickel to produce alloys in the aerospace, medical  and electronics industries.
