1. Aerospace field
Metal niobium has the characteristics of high-temperature strength, good oxidation resistance, and low thermal expansion coefficient, and can be used to produce high-temperature structural parts such as gas turbine blades and rocket engines. In addition, metal niobium can also be used to manufacture various elastic components required for aerospace, such as springs, springs, thin tubes, etc., and plays an important role in the aerospace field.
2. Electronic and electrical fields
Metal niobium has good electrical properties and superconducting properties and is widely used in the electronic and electrical fields. For example, niobium metal can be used to manufacture high-speed transistors, deep ultraviolet light-emitting diodes, piezoelectric transparent ceramics, and solar cells. In addition, metallic niobium can also be used in energy storage components, magnetic memories and other fields.
3. Energy field
Metal niobium is one of the important materials in the new energy industry and can be used to manufacture various components in solar energy, wind energy, hydro energy and other fields.

Preparation of niobium
Metal niobium can be produced by electrolysis of molten potassium heptafluoroniobate, by reduction of potassium heptafluoroniobate by metallic sodium or by reduction of niobium pentoxide by metallic aluminum. Pure niobium is used to remove residual gases in electron tubes. Doping niobium in steel can improve the oxidation resistance of steel at high temperatures and improve the welding performance of steel. Niobium is also used in the manufacture of high-temperature cermets.
vacuum carbon reduction method
The vacuum carbon reduction method is currently one of the main methods for producing metallic niobium at home and abroad. Carbon reduction is generally performed in a vacuum carbon tube furnace. This method utilizes the fact that the affinity of carbon for oxygen is greater than the affinity of niobium for oxygen, and uses carbon as a reducing agent to reduce Nb2O5 to produce niobium strips. Its advantages are high product yield (>96%), cheap reducing agent, low production cost, no by-products of sodium reduction and other methods that require wet treatment, and higher purity niobium bars and metal powders can be obtained.
There are two processes in industry: direct carbon reduction and indirect carbon reduction. The niobium produced by direct carbon reduction is sponge-like, has a large surface area, and has low metal impurities and nitrogen content, which is beneficial to the specific capacity of niobium powder. Therefore, this process is suitable for the production of capacitor-grade niobium powder. The characteristics of indirect reduction are large equipment production capacity, stable process, relatively dense metal niobium strips and regular appearance and dimensions, which is suitable for making niobium strips, niobium ingots and niobium processed materials.
