Niobium powders and niobium electrolytic capacitors

摘要

A flaked niobium powder is disclosed as well as electrolytic capacitors formed from the flaked niobium powders. Niobium powders having a BET surface area of at least about 0.50m<2>/g are also disclosed and capacitors made therefrom, as well as niobium powders doped with an oxygen content of at least 2,000ppm. Methods to reduce DC leakage in a niobium anode are also disclosed.
