Niobium powder and solid electrolytic capacitor |
摘要 |
By adding a slight amount component to a niobium powder, the leakage current of a solid electrolytic capacitor is reduced and the capacitance thereof is improved, and thereby a solid electrolytic capacitor large in the capacitance and small dielectric loss tangent is manufactured. Specific resolution means are as follows. With a niobium powder that contains 1 ppm or more and 600 ppm or less of hydrogen; 1 ppm or more and 200 ppm or less of carbon; or 1 ppm or more and 50 ppm or less of nickel, and the balance substantially made of niobium as a raw material, a sintered body thereof is formed as an anode in a solid electrolytic capacitor 10.
