摘要:
A Ta-Nb alloy powder which has provides a capacitor having a higher capacitance than a Ta capacitor and a better thermal stability in terms of an oxide film is better than a Nb capacitor, the Ta-Nb alloy powder being a Ta-Nb alloy powder produced by a thermal CVD method, wherein a content of Nb is 1 to 50 mass%, and an average particle diameter of primary particles is 30 to 200 nm, preferably, a CV value per unit mass of the powder (µF·V/g) is 250 kµF·V/g or more, or further, a CV value per unit volume (µF·V/mm 3 ) in terms of a molded body whose molding density ρ (g/cm 3 ) is ρ c (g/cm 3 ) = -0.012R Nb + 3.57, wherein R Nb : Nb content (mass%) in an alloy, is 900 µF·V/mm 3 or more, and an anode element for a solid electrolytic capacitor using the alloy powder.
