are widely used in chemical, electronic, aviation and aerospace fields due to their high melting point, corrosion resistance, and good cold working performance. Niobium rods are used as structural materials and rocket nozzles for aero engines, internal components and sheath materials for reactors, and various corrosion-resistant parts for the production of nitric acid, hydrochloric acid or sulfuric acid corrosion conditions. The addition of zirconium to niobium can significantly improve the oxidation resistance and strength of the material, and niobium and niobium-zirconium alloy wires are widely used in the manufacture of high-pressure sodium lamps and anode leads of electrolytic capacitors.

1.They are used to make corrosion-resistant electrodes and other corrosion-resistant parts in the strong acid and alkali chemical industry,; they are widely used in aerospace, medical equipment and other fields. It is a rare metal element in the earth's crust and the soul component of the high-tech industry. The world's largest niobium mine is in Brazil, and a new niobium mine has been discovered in Baotou, Inner Mongolia, China, which has become a superpower in resource development. Niobium refining methods include oxidative roasting and leaching, which are widely used in aerospace, petroleum, electronics, medical and other fields, and are of great significance to enhance the overall strength of the country.

2. are made of niobium, which is the soul of many high-tech industries, although it only accounts for 0.002% of the total crust. Imagine that, like diamonds in jewelry, niobium is the jewel of the industrial world.
