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.
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 ...
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 National Livestock Identification System (NLIS) of Australia regulations require that all cattle be fitted with a RFID device in the form of an ear tag or rumen bolus (a cylindrical object placed in the rumen) [2] [3] before movement from the property and that the movement be reported to the NLIS. However, if animals are tagged for internal ...
Niobium has many uses, some of which it shares with other refractory metals. It is unique in that it can be worked through annealing to achieve a wide range of strength and ductility, and is the least dense of the refractory metals. It can also be found in electrolytic capacitors and in the most practical superconducting alloys. Niobium can be ...
The development of quantitative methods for livestock production includes mathematical modelling based in plant-herbivore or predator-prey models to forecast and optimise meat production. An example is the Predator-Prey Grassland Livestock Model (PPGL) [7] to address the dynamics of the combined grass-animals system as a predator-prey dynamical ...
