Niobium (chemical symbol Nb, atomic number 41) is a transition metal element. Pure niobium is a lustrous grey metal. High-purity niobium is highly ductile, and its ductility reduces as the level of impurities increases. Niobium possesses a very low thermal neutron capture cross-section, making it extremely well-suited for nuclear industry applications.
