Niobium powder

Niobium (Nb) is the lightest refractory metal with a high melting point and high-temperature strength. Niobium powder with a layer of dense oxide film formed on its surface has the properties of unidirectional conductive value and specific capacitance for capacitor. So Niobium (Nb) powder is widely used for the manufacture of electrolytic capacitors and walkie-talkies and general industrial electrical equipment. It also can be used for high temperature parts, alloys, spray coating, filter and corrosion resistant applications. It can be prepared by reduction-hydrogenation method, sodium reduction method, and also plasma spheroidization, plasma rotating electrode process (PREP).
