    • An object of the present invention is to provide a niobium oxide that is suitable for application to capacitors, high in purity, large in specific surface area and small in particle size. The present invention also provides a method for producing such a high-purity niobium oxide. The present invention provides a niobium oxide that is a low oxidation number niobium oxide obtained from a high oxidation number niobium oxide, characterized in that the niobium oxide has a specific surface area (BET value) of 2.0 m2/g to 50.0 m2/g. The production method comprising dry reducing niobium pentoxide to produce niobium monoxide is characterized in that the reduction treatment is carried out stepwise in two steps. In the stepwise reduction, it is preferable that a carbon-containing reducing agent be used at least in any one of the two steps, and the temperature and the ambient pressure be maintained in a predetermined range in each of the steps.
    • 本发明的目的是提供一种适用于高纯度,比表面积大,粒径小的电容器的铌氧化物。 本发明还提供了这种高纯度铌氧化物的制造方法。 本发明提供一种氧化铌氧化物,其是由高氧化铌氧化物获得的低氧化铌氧化物,其特征在于,所述铌氧化物的比表面积(BET值)为2.0m 2以上, g至50.0 m 2 / g。 包含干燥还原铌五氧化物以制备铌一氧化铌的制备方法的特征在于还原处理分两步进行。 在逐步还原中,优选至少在两个步骤中的任一个中使用含碳还原剂,并且在每个步骤中将温度和环境压力保持在预定范围内。
