Application Of Niobium

2024-01-05 18:00:06

  Iron and steel industry

  Approximately 85% to 90% of niobium in the world is used in the production of iron and steel . Only 0.03% to 0.05% niobium is added to the steel so that the yield strength of the steel can be increased by more than 30%. it can also induce precipitation and control cooling rate to realize precipitation dispersion and adjust the toughness level of steel in a wide range. Therefore, the addition of niobium in steel can not only improve the strength of steel, but also improve the toughness, high temperature oxidation resistance and corrosion resistance of steel, reduce the brittle transition temperature of steel, so that steel has good weldability and formability.

  * superconducting materials industry

  Some compounds and alloys of niobium have high superconducting transition temperatures, so they are widely used to manufacture various industrial superconductors, such as superconducting generators, accelerators, high-power magnets, superconducting magnetic energy storage, nuclear magnetic resonance imaging equipment, etc. Nowadays, the most important superconductors are Niobium-Titanium and niobium-tin, which are widely used in magnetic resonance imaging (MR) and NMR spectroscopy.

 

   Aerospace Industry

   The aerospace industry is the main application field of high-purity niobium, mainly used in the production of rockets, spacecraft engines and heat-resistant components. Nb and Ta heat-strengthening alloys have good thermal strength, heat resistance and processing properties, and are widely used to manufacture aero-engine parts and gas turbine blades. Almost all jet fighters in the United States use NB alloys for their thermal components.

  Atomic energy industry

  Nb has good thermal conductivity, high melting point, good corrosion resistance, and low neutron capture cross section. It is a very suitable material for nuclear reactor. The main uses of niobium in the atomic energy industry include: nuclear fuel cladding materials, nuclear fuel alloys, nuclear reactor heat exchanger structural materials.
