Niobium-titanium is a superconducting at temperatures below ten Kelvin and is used in a number of large superconducting magnets such as the Tevatron accelerator at Fermilab and most recently the Large Hadron Collider, where the niobium-containing magnets are cooled to 1.9 Kelvin and operate at magnetic fields of up to 8.3 Tesla.
One of our magnetic separators here at Master Magnets includes the Rare Earth Roll. This is used for the purification of dry fine or course material containing …
Apr 24, 2017· Niobium (Nb) is a rare metal, a transitional element and the 33rd most common element on the earth's crust. Niobium is important to modern society because niobium alloys are used frequently in both steel-based construction and scientific equipment, especially equipment designed to …
Niobium-Titanium Superconductor Niobium-titanium is a Type-II superconductor with a critical temperature of 10 K and a critical magnetic field of 15 Tesla. While both of these values are lower than those for niobium-tin, this material has become the material of choice for superconducting magnets because of its mechanical properties.
SUPERCONDUCTING PROPERTIES OF NIOBIUM FILMS by Wayne R. Hudson and Russell J. Jirberg Lewis Research Center SUMMARY Critical currents as a function of magnetic field, film thickness, and film orienta tion have been studied for 14 niobium films ranging in thickness from 16.2 to 1153 nanometers (16.2 to 11 530 A). All measurements were made at 4.2 K.
Niobium has the greatest magnetic penetration depth of any element. In addition, it is one of the three elemental Type II superconductors, along with vanadium and technetium. The superconductive properties are strongly dependent on the purity of the niobium metal.
The effect of niobium content on the magnetic properties of these bonded magnets was investigated. Niobium has a significant effect on the magnetic behaviour of these hydrogen-processed materials. Best overall magnetic properties were obtained in a Pr 14 Fe 63.9 Co 16 B 6 Nb 0.1 magnet.
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.. In 1962, at Atomics International, T. G. Berlincourt and R. R. Hake, discovered the superior high-critical-magnetic-field, high-critical ...
also in the pure elements niobium and vanadium (13,14). One can understand the reason for the broad magnetic transition in type-l! superconductors from consideration of the magnetic Gibbs free energy difference at a normal- superconducting interface. Figure 2 shows the dependence of both the magnetic field and the order parameter at such an
