用途ファインセラミックス、圧電材料。
説明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.
使用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.
Niobium pentoxide is produced as an intermediate during recovery of Nb metal from ores (See niobium). Also, the pentoxide may be produced by igniting niobium metal powder, niobium carbide, or niobium fluoride in oxygen.

化学的特性Niobium(V) oxide is a white crystalline powder that turns light yellow upon exposure to oxygen. It is insoluble in water and most acids but soluble in molten potassium hydrogen sulfate or alkali metal carbonate and hydroxide.Its hydrate has the chemical formula Nb₂O₅·xH₂O. It decomposes upon heating and is soluble in concentrated sulphuric acid, concentrated hydrochloric acid, hydrofluoric acid, and strong acids. It is insoluble in water and ammonia solution. It can be obtained by calcining metallic niobium in air or by dehydrating niobium oxide.
