Suggestions In Using Niobium
Niobium and alloyed niobium have a high melting point, corrosion resistance, good cold processing properties and other superb features. It has been more and more widely used in chemical, electronic, electric light source, aerospace and other areas.
Niobium's chemical features are similar with tantalum. Except fluorine, hydrofluoric acid, acid solution contained fluorine ions, fuming sulfuric acid and strong alkalis, it won't corrode im most media. Therefore, niobium and alloyed niobium are largely used in making chemical industries' reaction vessels, heat exchangers as well as sodium electrical conduit of high pressure in lighting source industry.
Niobium has small density, high melting point, good formability and thermal neutron captures small cross-sections and other excellent features, having good applications and perspectives. Niobium-based alloys of high temperature are widely applied to aerospace industry. FS-85, C103 these two alloys are separately used by spaceship engine's structural materials and rocket nozzles, heat exchangers and so on. Nb-1Zr can also be used in reactors inner elements, packaging materials and so on.
"Niobium and niobium zirconium alloys are used in making sodium lamp of high pressure in electronic industry. Adding zirconium to niobium can obviously raise materials' inoxidizability and intensity. Most niobium zirconium alloys are processed into wires used in making sodium lamps’ electrical conduits of high pressure. Nowadays, using niobium wires to replace niobium capacitors’ anticathode fuse is rising. Expensive tantalum wires have been taken place by niobium wires in a low-voltage scope and this tendency is becoming bigger and bigger.
Niobium Used In Other Ways
Like tantalum, niobium can be also used in making vacuum furnaces’ attachments and supports of high temperature in technical ways. Niobium of high purity, NbTi, Nb3Sn and so on. Alloyed niobium is also a good superconductor. The surface of metals will show different colors due to different amount of oxygen. So, niobium is also applied to jewelry manufacturing industry.
