• Description: Niobium oxide (N2O5), also named as niobium pentoxide, is used in metallurgy to produce hard materials. Niobium pentoxide is added to the glass during the production of optical lenses to make the lenses lighter, thinner and with greater resilience. At the same time, niobium pentoxide increases the refractive index of optical glasses. In electronics, niobium pentoxide is used to produce multi-layered ceramic capacitors with high capacity and for the preparation of electroacoustic or electrooptical components such as LiNbO3 and KNbO3 or ferroelectric ceramics such as Pb(Mg1/3Nb2/3)O3. It is further used in making cathodes, as pigment in printing, packaging and solid fuels, in food processing industry as dietary supplements, and in the production of powder metallurgy products.
• Physical properties: White orthogonal crystals; density 4.60 g/cm3; melts at 1,512°C; insoluble in water; soluble in hydrofluoric acid.
• Uses: Niobium(V) oxide 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.
