Introduction to niobium components in niobium tubes
Niobium has a density of 8.57g/cm3, a melting point of 2477°C, and a boiling point of 4744°C. Niobium is a silver-grey, soft, ductile, rare, high-melting-point metal. At room temperature, niobium does not react with air, and will not be completely oxidized when red-hot in oxygen. Niobium can directly combine with sulfur, nitrogen, and carbon at high temperatures. Niobium does not react with inorganic acids or alkalis, nor does it dissolve in aqua regia, but is soluble in hydrofluoric acid. Because niobium has good superconductivity, high melting point, corrosion resistance, wear resistance, etc., it is widely used in steel, superconducting materials, aerospace, atomic energy and other fields.
