Niobium is a very important superconducting materil to producehigh-capacity capacitor.
|
Niobium powder is also used to produce tantalum.
|
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;
|
By adding 0.001% to 0.1% Niobium nano powder is good enough tochange the mechanical properties of steel
|
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.
