Niobium, formerly columbium, is a chemical element with the symbol Nb and atomic number 41. Melting point 2468℃, boiling point 4742℃. It is a soft, grey, ductile transition metal. Niobium has physical and chemical properties similar to those of the element tantalum. It was not until the early 20th century that niobium was first used commercially. Niobium is used mostly in alloys, the largest part in special steel such as that used in gas pipelines. Although alloys contain only a maximum of 0.1%, that small percentage of niobium improves the strength of the steel. The temperature stability of niobium-containing superalloys is important for its use in jet and rocket engines. Niobium is used in various superconducting materials. These superconducting alloys, also containing titanium and tin, are widely used in the superconducting magnets of MRI scanners. 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.
