About Pure Niobium Metal (Nb) and Niobium Alloys

ਨਿਓਬੀਅਮ, also known as Columbium, is a shiny gray or silvery ductile metal that does not tarnish or oxidize at room temperature. Niobium reacts with oxygen and halogens only when heated. Niobium is less corrosion-resistant than tantalum at high temperature. Niobium is not attacked by nitric acid up to 100 . ਸੀ, but aggressively attacked by mixture of nitric and hydrofluoric acids. Hot, concentrated hydrochloric, sulfuric, and phosphoric acids attack it, but hot, concentrated nitric acid does not.

Niobium is unaffected at room temperature by most acids. It is attacked by alkaline solutions to some extent at all temperatures. 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.
