Atomic No. 41 Nb Niobium

About Niobium

Niobium is a transition metal with atomic number 41 that commonly forms compounds in the +5 oxidation state. It is used in specialized steels and superconducting alloys, while niobates contribute to optical and electronic ceramics. Nickel niobate is investigated in dielectric ceramic compositions and as an electrode material for lithium ion batteries, illustrating how niobium containing oxides can support both electronic components and electrochemical energy storage.
