Certain compounds and alloys of niobium have high superconducting transition temperatures and are therefore widely used in the manufacture of various industrial superconductors, such as superconducting generators, high-power magnets for accelerators, superconducting magnetic energy storage devices, nuclear magnetic resonance imaging equipment, etc. . Currently, the most important superconductor materials are niobium-titanium and niobium-tin, which are widely used in magnetic resonance imaging instruments for medical diagnosis and nuclear magnetic resonance instruments for spectral line analysis.
The aerospace industry is the main application area of high-purity niobium, mainly used in the production of rockets, spacecraft engines and heat-resistant components. Thermal-strength alloys of niobium and tantalum have good thermal-strength properties, heat resistance and processing properties, and are widely used in the manufacture of aero-engine parts and gas turbine blades.
Niobium has good thermal conductivity, high melting point, good corrosion resistance, and low neutron capture cross section, making it a very suitable material for atomic energy reactors. The main uses of niobium in the atomic energy industry include: cladding materials for nuclear fuel, alloys for nuclear fuel, and structural materials for heat exchangers in nuclear reactors.
