General description
氧化铌(V)，也称五氧化铌，是一种白色结晶粉末。它是一种熔点超过2500 °C的难熔金属氧化物，对氧和水有高化学稳定性。氧化铌(V)主要作为生产铌和铌合金的原料，作为化学反应的催化剂，也可作为高温度应用中的难熔材料。它也可用作电容器中的介电材料以及陶瓷和玻璃中的颜料。
Application
在一个不寻常的阳离子缺乏钙钛矿的固态形成中应用，Ba7Nb4MoO20。
在高级燃料电池中使用氧化铌(V) 替代金属锂电极已得到令人满意的效果。
Features and Benefits
用于非常规阳离子缺陷型钙钛矿 Ba7Nb4MoO20 的固态形成。

A film of niobium oxide was immobilized on a SiO(2)/C carbon-ceramic matrix (specific surface area 270 m(2)g(-1)) and characterized by N(2) adsorption-desorption isotherms, scanning electron microscopy, X-ray photoelectron spectroscopy and atomic force microscopy. This new carbon-ceramic material, SiO(2)/C/Nb(2)O(5), was used
