As a material with high biocompatibility and physicochemical properties, niobium has been applied to different subfields of stomatology and plays different roles. Due to its relatively low elastic modulus and strong corrosion resistance, niobium has been applied to implant, repair, orthodontic and maxillofacial surgery. Because of the high transmittance of radiation, it is used in oral medicine and radiology.
Niobium is widely used in iron and steel industry, aerospace industry, superconducting materials and other fields. About 85% ~ 90% of niobium in the world is used in steel production in the form of niobium, which can increase the yield strength of steel by more than 30% and adjust the toughness level of steel by adding only 0.03% ~ 0.05% niobium. Niobium steel is widely used in automobile, bridge, oil pipeline, natural gas pipeline, oil drilling, offshore oil drilling platform, railway, civil construction steel bar and so on.
High purity niobium is widely used in the aerospace field, mainly for the production of rockets, spacecraft engines and heat-resistant components, almost all jet fighter engines are made of niobium alloy.
Some compounds and alloys of niobium have high superconducting transition temperature, so they are widely used in manufacturing various industrial superconductors. At present, almost all industrial superconducting devices adopt NbTi and Nb3Sn as superconductors, such as superconducting generators, high-power accelerator magnets, superconducting magnetic energy storage devices, mri equipment, etc.
