Niobium–titanium (Nb-Ti) is an alloy of niobium and titanium, used industrially as a type II superconductor wire for superconducting magnets, normally as Nb-Ti fibres in an aluminium or copper matrix. Its critical temperature is about 10 kelvins. [1]
Niobium–tin superconducting wire from the ITER fusion reactor, which is currently under construction.. Niobium-tin and Niobium-titanium are essential alloys for the industrial use of superconductors, since they remain superconducting in high magnetic fields (30 T for Nb 3 Sn, 15 T for NbTi); there are 1200 tons of NbTi in the magnets of the Large Hadron Collider, whilst Nb 3 Sn is used in ...
Most commonly, conventional superconductors such as niobium–titanium are used, [1] but high-temperature superconductors such as YBCO are entering the market. Superconducting wire's advantages over copper or aluminum include higher maximum current densities and zero power dissipation.
Niobium is used in arc welding rods for some stabilized grades of stainless steel [122] and in anodes for cathodic protection systems on some water tanks, which are then usually plated with platinum. [123] [124] Niobium is used to make the high voltage wire of the solar corona particles receptor module of the Parker Solar Probe. [125]
The first successful superconducting magnet was built by G.B. Yntema in 1955 using niobium wire and achieved a field of 0.7 T at 4.2 K. [10] Then, in 1961, J.E. Kunzler, E. Buehler, F.S.L. Hsu, and J.H. Wernick made the discovery that a compound of niobium and tin could support critical-supercurrent densities greater than 100,000 amperes per ...
Midland PA Works. ATI Inc. (previously Allegheny Technologies Incorporated) is an American producer of specialty materials headquartered in Dallas, Texas.ATI produces metals including titanium and titanium alloys, nickel-based alloys and superalloys, stainless and specialty steels, zirconium, hafnium, and niobium, tungsten materials, forgings and castings.
The main source of niobium until now has been from the ore mineral columbite that is extracted widely in Canada, Brazil, Australia and Nigeria, with China obtaining nearly 95 per cent of the ...
Niobium–tin is an intermetallic compound of niobium (Nb) and tin (Sn), used industrially as a type-II superconductor. This intermetallic compound has a simple structure: A3B . It is more expensive than niobium–titanium (NbTi), but remains superconducting up to a magnetic flux density of 30 teslas [T] (300,000 G), [ 1 ] compared to a limit ...
