Using
Details of aircraft and rocket engines; nuclear accelerators, shells of nuclear boilers (niobium carbide, melting point 3480 ° C), containers for molten metals and storage of radioactive waste. This metal is in demand in the production of electrolytic capacitors; cathodes, anodes, grids of powerful generator lamps. Heat carriers in nuclear reactors (liquid potassium and sodium) move along niobium tubes. Alloys doped with niobium produce chemical equipment. They are alloyed with chromium steels. He also found application in cryotrons — superconducting components of computers.
