NIOBIUM ALLOY, SINTERED BODY THEREOF, AND CAPACITOR USING THE SAME |
摘要 |
The present invention relates to a niobium alloy for capacitors comprising as an alloy component from 0.01 to 10 atom of at least one element selected from the group consisting of the elements belonging to Groups 2 to 16 of the periodic table and further comprising diniobium mononitride crystals of from 0.1 to 70 mass %, wherein a powder of the niobium alloy has an average particle size of 0.05 to 5 μm and a BET specific surface area of 0.5 to 40 m2/g, a granulated product of the niobium alloy having an average particle size of 10 to 500 μm, a sintered body of the powder of the niobium alloy or granulated product thereof, a capacitor and a producing method thereof using the sintered body. A niobium capacitor using the powder of the niobium alloy of the present invention or a granulated product thereof has high capacitance and small leakage current value and is excellent in high-temperature property and heat resistance property.
