Note: Niobium can withstand high temperature and high strength, and still has sufficient strength, plasticity and thermal conductivity above 1000°C. Superconductivity is best at extremely low temperatures. For example, its resistance is close to zero at minus 260°C. It is currently the most important superconducting material.
Application: Niobium and niobium alloy rods and wires are widely used in the fields of chemistry, electronics, aviation and aerospace due to their high melting point, corrosion resistance, and good cold working performance. Niobium and niobium alloy bars are used as structural materials for aircraft engines and rocket nozzles, reactor internal components and cladding materials, and for the production of various corrosion-resistant parts under the corrosion conditions of nitric acid, hydrochloric acid or sulfuric acid. The addition of zirconium to niobium can significantly improve the oxidation resistance and strength of the material. Niobium and niobium-zirconium alloy wires are widely used in the manufacture of high pressure sodium lamps and anode leads of electrolytic capacitors.
