Product Name:Niobium
English Name:Niobium
CAS No.:7440-03-1
Aliases:Niobium metal
Molecular Formula:Nb
Physical Properties:Melting point 2468°C, boiling point 4742°C, density 8.57 g/cm³. Stable in air at room temperature, not completely oxidized even when red-hot in oxygen. Combines directly with sulfur, nitrogen, and carbon at high temperatures, and forms alloys with titanium, zirconium, hafnium, and tungsten. Not attacked by inorganic acids or alkalis.
Uses:Niobium is an important superconducting material with high critical temperature alloys, widely used in superconducting magnets. It is also extensively used in production of nickel, chromium, and iron-based superalloys for jet engines, gas turbines, and rocket components. In steel industry, niobium serves as an efficient microalloying element that significantly improves mechanical properties of steel. Additionally, niobium is used in high-pressure sodium lamp arc tube seals and commemorative coins.
Technical Specifications:
Melting point: 2468°C
Boiling point: 4742°C
Density: 8.57 g/cm³
Packaging: 100g/500g/1kg/5kg
Storage: sealed under inert gas, keep in dry and cool place
