POWDER FOR CAPACITOR, SINTERED BODY THEREOF AND CAPACITOR USING THE SINTERED BODY |
摘要 |
A powder for capacitors, which contains 0.01 to 15 atom % of zirconium and mainly comprises niobium and/or tantalum having an average particle size of from 0.2 to 5 mu m; a sintered body thereof; an a capacitor fabricated from the sintered body as one part electrode, a dielectric material formed on the surface of the sintered body, and another part electrode provided on the dielectric material. A capacitor manufactured from the sintered body of a powder for capacitors of the present invention have a large capacitance per unit mass and good leakage current characteristics. |
