Note: We can supply different size products of Spherical ultrafine niobium powders according to client's requirements.
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.
Application of ultrafine niobium powders:
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. Such alloy is applied to jet engines, gas turbine engines, rocket assembly, the turbocharger and the heat of combustion equipment;
4. By adding 0.001% to 0.1% Niobium nano powder is good enough to change the mechanical properties of steel
5. Due the coefficient of thermal expansion of Niobium is very similar to the sintered alumina ceramic material of the arc lamp, Nb nano powder could used as sealed material of the arc tube
SEM & XRD of ultrafine niobium powders:
Storage conditions:
ultrafine niobium powders should be sealed and stored in a dry and cool environment. It should not be exposed to the air for a long time, to prevent agglomeration due to moisture, affecting the dispersion performance and use effect, and should avoid heavy pressure, do not contact with oxidant, and transport according to ordinary goods.
