Niobium

Niobium is a ductile transition metal. It is found in the minerals pyrochlore, the main commercial source for niobium, and columbite. It is used mostly in alloys, the largest part in special steel such as that used in gas pipelines. The temperature stability of niobium-containing superalloys is important for its use in jet and rocket engines. Niobium is used in various superconducting materials. Other applications of niobium include its use in welding, nuclear industries, electronics, optics, numismatics and jewelry. In the last two applications, niobium's low toxicity and ability to be colored by anodization are particular advantages.
