Abstract
The present invention relates to capacitor anodes containing a niobium oxide having an atomic ratio of niobium to oxygen of 1:less than 2.5 and being formed at a formation voltage of about 6 volts or higher. The present invention further relates to a niobium oxide having an atomic ratio of niobium to oxygen of 1:less than 2.5, and having a nitrogen content of from about 31,000 ppm N2 to about 130,000 ppm N2. Capacitors containing the various types of niobium oxide are further described.
