Niobium is a chemical element with the symbol Nb and atomic number 41.

Niobium is a rare, soft, ductile off-white transition metal commonly found in the mineral pyrochlore (the main commercial source of niobium) and niobium ore. It has a body-centered cubic crystal structure and its physical and chemical properties are similar to tantalum. Even when processed at moderate temperatures, it must be placed in a protective atmosphere because it tends to react with oxygen, carbon, halogens, nitrogen and sulfur. The metal is inert to acids, even to aqua regia at room temperature, but is attacked by heat, concentrated acids, especially alkalis, and oxidizing agents.
Niobium is used in various superconducting materials, and these superconducting alloys also contain titanium and tin and are widely used in superconducting magnets in MRI scanners. Niobium is also used in welding, the nuclear industry, electronics, optics, numismatics and jewelry. In the last two applications, the low toxicity and iridescence produced by anodizing are highly desirable characteristics.
