Niobium Oxides (Nb₂O₅, NbO₂, NbO)

Niobium oxides (NbO, NbO₂, Nb₂O₅) are versatile materials with outstanding electrical, mechanical, chemical, and magnetic properties.
Niobium (V) Oxide, Nb2O5 (Niobium pentoxide), is colorless and insoluble. A fairly unreactive solid that is the most widespread precursor for other compounds and materials containing niobium.
Niobium (II) Oxide, NbO (Niobium monoxide), is a gray solid with metallic conductivity.
Niobium (IV) Oxide, NbO₂ (Niobium dioxide), is a bluish-black non-stoichiometric solid that is insoluble in water and is a powerful reducing agent.
Typical Applications

Niobium(V) Oxide, Nb₂O₅ is used mainly in the production of niobium metal, specialized applications in the production of optical glasses and niobium electrolytic capacitors. It is also considered for use as an anode in a lithium-ion battery.
Niobium(IV) Oxide, NbO₂, is a reducing agent.
