<p>A process for producing capacitor grade powder, electrodes, and finished capacitors therefrom having reduced electrical leakage characteristics. The powder is prepared by reacting Group V-B base materials with quantities of between 500 to 7000 ppm of nitrogen and 700 to 3000 ppm of oxygen. Electrical leakage is reduced by at least 28 % for electrodes anodized at 100 volts or greater in comparison with electrodes and finished capacitors made from undoped materials. A range of specific charge of up to 25,000 uFV/g is achieved for sintering temperatures of 1400 °C to 1800 °C.</p> |
