Niobium powder, the powder of metallic niobium, has a dense oxide film on its surface with unidirectional conductive valve metal properties.

Its oxide niobium oxide Nb2O5 is a white powder with a purity of up to 99.999%, which is used to produce high-purity lithium niobate crystals and special optical glass additives. This anodized film has stable chemical properties, high resistivity, small leakage current and large dielectric constant. The electrical properties of niobium powder for capacitors have a specific capacitance of 3300-3600μF·V/g and a leakage current value of 1×10-3μA/(μF·V). It is prepared by reduction-hydrogenation method, sodium reduction method, etc. It is used to manufacture electrolytic capacitors, walkie-talkies and general industrial electrical equipment.

PRODUCT USE

Niobium is a transition metal element with many wide applications and synthesis methods.

Niobium is widely used in alloy manufacturing. Niobium is also used to manufacture stainless steel and corrosion-resistant alloys.

Secondly, niobium has important applications in the electronics industry. Niobium can be used to manufacture components such as resistors, capacitors and inductors. Niobium compounds can also be used to make optoelectronic devices and semiconductor devices.

Niobium also has medical applications. Niobium is often used as an auxiliary material in radiotherapy and disease diagnosis in the medical field. Niobium's radioactive isotope niobium-94 is widely used in tumor treatment and radiotherapy.
