A sheet of niobium
Niobium is a chemical element. It is sometimes named columbium. It has the chemical symbol Nb. It has the atomic number 41. It is a rare metal. Niobium is soft and grey. It is ductile. In chemistry it is placed in a group of metal elements named the transition metals. Niobium was discovered in a variety of a mineral called columbite (now called niobite). Niobite is an ore of niobium.[1]
Niobium is considered a technology-critical element. It is used in alloys, such as to make special steels and strong welded joints. Less than 0.1% of Niobium significantly improves the strength of steel.[2] It is in the superconducting alloys used in MRI scanners, which are one of the most important medical inventions of the modern age.
