Niobium
Chemical elementNiobium is a chemical element; it has symbol Nb and atomic number 41. It is a light grey, crystalline, and ductile transition metal. Pure niobium has a Mohs hardness rating similar to pure titanium, and it has similar ductility to iron.
Niobium pentoxide
CompoundsNiobium pentoxide is the inorganic compound with the formula Nb₂O₅. A colorless, insoluble, and fairly unreactive solid, it is the most widespread precursor for other compounds and materials containing niobium.
Niobium(V) chloride
CompoundsNiobium(V) chloride, also known as niobium pentachloride, is a yellow crystalline solid. It hydrolyzes in air, and samples are often contaminated with small amounts of NbOCl₃. It is often used as a precursor to other compounds of niobium. NbCl₅ may be purified by sublimation.
Niobium–tin
CompoundsNiobium–tin is an intermetallic compound of niobium and tin, used industrially as a type-II superconductor. This intermetallic compound has a simple structure: A3B.
Isotopes of niobium
Naturally occurring niobium is composed of one stable isotope. The most stable radioisotope is ⁹²Nb with a half-life of 34.7 million years. The next longest-lived niobium isotopes are ⁹⁴Nb and ⁹¹Nb with a half-life of 680 years. There is also a meta state of ⁹³Nb at 31 keV whose half-life is 16.13 years. Twenty-seven other radioisotopes have been characterized. Most of these have half-lives that are less than two hours, except ⁹⁵Nb, ⁹⁶Nb and ⁹⁰Nb.
Niobium nitride
CompoundsNiobium nitride is a compound of niobium and nitrogen with the chemical formula NbN. At low temperatures NbN becomes a superconductor, and is used in detectors for infrared light.
