Perspectives over the Brazilian Iron-Niobium Production
Journal Title: Archives of Organic and Inorganic Chemical Sciences - Year 2018, Vol 1, Issue 1
Abstract
Niobium is a chemical element, symbol Nb, atomic number 41 (41 protons and 41 electrons) and atomic mass 92.9 u. It is a transition element belonging to the group 5 or 5B of the periodic classification of the elements. The name derives from the Greek goddess Níobe, daughter of Dione and Tantalus - the latter, in turn gave name to another element of the family 5B, tantalum. It is used mainly in alloys of steel for the production of conductive tubes of fluids. Under normal conditions, it is solid. It was discovered in 1801 by the Englishman Charles Hatchett [1].
