Cas 7440-03-1 Niobium Nb Metals 99.95% Niobium Powder
Cas 7440-03-1 Niobium Nb Metals 99.95% Niobium Powder
Niobium is gray metal, melting point 2468 ℃, boiling point 4742 ℃. Niobium is stable in air at room temperature, the red is not completely in the oxygen oxidation. Huarui provide the niobium powder ( Nb: 99% ~ 99.9% ) and ferro niobium powder ( Nb: 50% ~ 70% ). Particle size: 15-45um,45-120um.80-250um...etc
Application:
1. Niobium is a very important superconducting material to produce high-capacity capacitor.
2. Niobium powder is also used to produce tantalum.
3. The pure Niobium metal powder or Niobium Nickel alloy is used to make Nickel, Chrome and Iron base high
temperature alloy.
temperature alloy.
4. Adding 0.001% to 0.1% Niobium powder to change the mechanical properties of steel 5. Used as sealed material
