Product performance
Niobium is gray metal, melting point 2468 ℃, boiling point 4742 ℃, the density.Niobium stable in air at room temperature, the red is not be completely in the oxygen oxidation, high temperature directly combined with sulfur, nitrogen, carbon, can form with titanium, zirconium, hafnium, tungsten alloy.Not with inorganic acid or alkali, not soluble in aqua regia, but soluble in hydrofluoric acid.
Application direction
1. superconducting applications: niobium is the highest critical temperature superconducting properties of the elements.And made of niobium alloy, critical temperature as high as absolute temperature 18.50 to 210, is the most important superconducting material;
2. high temperature alloy in the world is very big niobium as pure metal or with high purity niobium and niobium iron nickel alloy, high temperature used in the production of nickel, chromium and iron base alloy.These alloys can be used for jet engines, gas turbines, rocket components, turbochargers and heat-resistant burning equipment;
3. steel application: all kinds of micro alloying elements in steel, niobium scrap is the most effective micro alloying elements, the effect of niobium is so big, so that the iron atom contains abundant niobium atoms, can achieve the purpose of improving steel performance.Adding 0.001% - 0.1% of the actual Shanghai niobium, is enough to change the mechanical properties of steel;
Storage conditions
This product should be stored in dry, cool and sealing of the environment, can not be exposure to air, in addition should avoid the heavy pressure, according to ordinary goods transportation.
