The powder of metal niobium, the dense oxide film formed on its surface has the property of unidirectional conductive valve metal.
Properties: Its oxide niobium oxide Nb2O5 is a white powder with a purity of 99.999%. It is used to produce high-purity lithium niobate crystals and additives for special optical glass. The anodic oxide film has stable chemical properties, high resistivity, small leakage current and large dielectric constant. The specific capacitance of niobium powder for capacitor is 3300~3600μF·V/g, and the leakage current value is 1×10-3μA/(μF·V). It is prepared by reduction-hydrogenation method, sodium reduction method, etc. Used in the manufacture of electrolytic capacitors and walkie-talkies and general industrial electrical equipment.
Application field
1 superconducting application;
2 high temperature alloy;
3 Steel applications:
4 coins;
5 Other niobium (or doped with 1% zirconium) is a sealing material for high pressure sodium lamp arc tubes because the thermal expansion coefficient of niobium is very similar to that of sintered alumina arc lamp ceramic materials
