Ferrous & Non-ferrous Alloy
Description
Description:
Niobium is a Block D, Group 5, Period 5 element. The number of electrons in each of Niobium& acute;s shells is 2, 8, 18, 12, 1 and its electronic configuration is [Kr] 4d4 5s1. In its elemental form niobium& acute;s CAS number is 7440-03-1. The niobium atom has a radius of 142.9.pm and it& acute;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.
Applications:
Ferro Niobium alloy is applied to steel making and foundry as additive. We add niobium to stainless and heat resistant steel so as to raise its plasticity and corrosion resistance of your product. We add niobium to structural steel to improve welding property of the structural steel and enhance its strength and plasticity to prevent welding seam from corrosion.
