Description
Niobium(V) Oxide Product Overview
Niobium pentoxide (Nb2O5) is a white, inert powder that is insoluble in water and melts at about 1512°C. It is the main oxide of niobium and the starting point for most niobium compounds.
Crystal growers combine it with lithium carbonate to grow Lithium niobate crystals for surface acoustic wave filters and electro-optic modulators. Optical glass producers add it to raise the refractive index of camera and smartphone lenses. Electronic ceramic producers use it in dielectrics and piezoceramics, often together with Titanium dioxide.
Niobium oxide is also a solid acid catalyst and is studied as a fast-charging anode material in lithium-ion batteries. For related oxides used in optics and electronics, see Lithium Tantalate.
