Niobium is a silver-colored metal that is generally found in conjunction with tantalum, the two elements being separated by fractional crystallization of their respective fluoro-complexes. It has an abundance of 20 ppm in the earth’s crust. As a pure metal, it is very reactive and forms an extremely stable oxide when exposed to air which enhances its corrosion resistance. Niobium will react with a variety of non-metals at elevated temperatures.

Steel production:
Niobium is an effective microalloying element for steel, within which it forms niobium carbide and niobium nitride. These compounds improve the grain refining, and retard recrystallization and precipitation hardening. These same niobium alloys are often used in pipeline construction.
Superalloys:
Quantities of niobium are used in nickel-, cobalt-, and iron-based superalloys in proportions as great as 6.5% for such applications as jet engine components, gas turbines, rocket subassemblies, turbocharger systems, heat-resisting, and combustion equipment. Niobium precipitates a hardening γ”-phase within the grain structure of the superalloy.
Superconducting magnets:
Niobium-germanium (Nb3Ge), niobium-tin (Nb3Sn), as well as the niobium-titanium alloys are used as a type II superconductor wire for superconducting magnets. These superconducting magnets are used in magnetic resonance imaging and nuclear magnetic resonance instruments as well as in particle accelerators.
