  • Inorganic Compounds
    Publication number: 20080199393
    Abstract: Disclosed is a niobium suboxide powder for the manufacture of capacitors with higher break down voltages, higher temperatures of operation and elongated lifetimes. The powder is doped with nitrogen which is at least partly present in the form homogeneously distributed, x-ray detectable Nb2N-crystal domains. The niobium suboxide powder contains niobium suboxide particles having a bulk nitrogen content of between 500 to 20,000 ppm.
