uses of niobium pipe
Niobium and niobium alloy tubes, rods and wires are widely used in chemistry, electronics, aviation and aerospace because of their high melting point, corrosion resistance and good cold working performance. Niobium and niobium alloy bars are used as structural materials of aero-engines, rocket nozzles, internal components of reactors and cladding materials, and only corrosion-resistant parts can be made under the conditions of corrosion resistance of nitric acid, hydrochloric acid or sulfuric acid. Adding zirconium to niobium can obviously improve the oxidation resistance and strength of materials. Niobium and niobium-zirconium alloy wires are widely used to manufacture high-pressure sodium lamps and anode leads of electrolytic capacitors.
Description of niobium
Metal niobium can be prepared by melting potassium heptafluoroniobate by point decomposition, or by reducing niobium pentoxide with sodium metal potassium heptafluoroniobate or aluminum metal. Pure niobium is used to remove residual gas in electron tubes. Doping niobium in steel can improve the oxidation resistance of steel at high temperature and improve the weldability of steel.
With the continuous progress of science and technology and the optimization and upgrading of industrial structure, the application field of niobium will continue to expand. In the future, niobium is expected to play its unique advantages in more fields and promote the rapid development of related industries. At the same time, with the continuous development and utilization of niobium resources in China, the output and quality of niobium will also be improved to further meet the market demand.
In a word, the main uses of niobium in China cover steel, aerospace, new energy and other fields, and it has a wide application prospect and huge market potential. In the future, with the progress of science and technology and industrial development, niobium will play an important role in more fields and make greater contributions to the country's economic development and social progress.
