Overview and application of Niobium

Niobium is suitable as the structural material for reactor and coating material for nuclear fuel as well as the thermal protection and structural material adapted in aerospace industry. In the Metallurgical industry, Niobium is mainly used as additive to produce high strength alloy steel, to improve properties of various alloys and to make super hard tools.
Niobium also plays an important role in surgical field, which can not only be used to manufacture medical devices, but also be a good "Biocompatible Material". Niobium can constitute alloys with various elements, which have important applications in various industries.
For example, Niobium Titanium alloy, Niobium Zirconium alloy, Niobium Tin, Niobium Aluminum germanium and other compound superconducting materials are used not only for power transmission, power generation, manufacturing superconducting magnets and controlling nuclear fusion, but also for navigation devices in space aircraft, electromagnetic propulsion equipment for high-speed diving ships and superconducting super-class high-speed trains. Niobium alloy is also an advantageous material which can be used to make components of supersonic ramjet engines.
