Niobium(V) oxide, 99.5% (metals basis)

Description

For Use As An Intermediate and in Electronics | CAS: 1313-96-8 | Nb2O5 | 265.81 g/mol

As an intermediate and in electronicsNiobium pentoxide is the precursor to a majority of niobium compounds, powder metallurgy products and alloys. It is also used in glass, optic and ceramic applications. The nanoparticles of niobium pentoxide are useful in the preparation of electrochemical capacitors and cathodes. In addition, appropriate preparations of this compound can be used as a dietary supplement in the food industry. It is a precursor to lithium niobate which finds extensive use in piezoelectric sensors, anti-aliasing filters, optical waveguides, mobile phones, surface acoustic devices, optical modulators including linear and non-linear optical applications.
