Niobium Powder (Nb Powder) Description
Niobium powder (CAS No. 7440-03-1) is steel-gray or silvery-white but becomes blue after prolonged exposure to air at room temperature. The metal's oxidation in air commences at 200°C. Niobium, when used in alloying, improves strength. When combined with zirconium, its superconductivity is enhanced.
Niobium is a strong rare earth metal with excellent properties such as high specific gravity, high impact strength, high strength, fatigue resistance, and corrosion resistance Metallurgical niobium powder is mainly used as an additive, in the manufacture of special welding rods and hot products.
