摘要： An object of the present invention is to provide a niobium sintered body free of reduction in the CV value, a niobium powder for use in the manufacture of the niobium sintered body, and a capacitor using the niobium sintered body. A niobium powder of the present invention has niobium and tantalum, where the tantalum is present in an amount at most of about 700 ppm by mass. A sintered body and a capacitor each is manufactured using the niobium powder.

摘要： A powder composition for a capacitor comprising a tantalum or niobium and a compound having a silicon-oxygen bond, at least a part of which may be nitrided and which has an average particle size of from 0.1 to 5 μm; a sintered body using the composition; and a capacitor constituted by the sintered body as one part electrode, and another part electrode. A capacitor favored with high reliability, lower dissipation level of power and smaller deterioration of capacitance than conventional tantalum capacitors using tantalum can be produced by using a sintered body of the powder composition for a capacitor.
