Beschreibung

Allgemeine Beschreibung

Niobium(V) oxide, also known as niobium pentoxide, is a white crystalline powder. It is a refractory metal oxide with a high melting point of over 2500 °C and high chemical stability, including to oxygen and moisture. Niobium(V) oxide is mainly used as a raw material in the production of niobium and niobium alloys, as a catalyst in chemical reactions, and as a refractory material in high-temperature applications. It is also used as a dielectric material in capacitors and as a pigment in ceramics and glasses.

Anwendung

Applied in the solid state formation of an unusual cation deficient perovskite, Ba₇Nb₄MoO₂₀.

Promising results were obtained using niobium(V) oxide as an alternate electrode to lithium metal in advanced fuel cells.
