General description
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.
Application
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.
Features and Benefits
Applied in the solid state formation of an unusual cation deficient perovskite, Ba7Nb4MoO20.
