Abstract
A process for forming a solid tantalum capacitor is disclosed wherein the cathode is manganese dioxide formed by pyrolysis. The pyrolysis is performed in a nitrogen dioxide containing atmosphere at a temperature of between about 170.degree. C. and 250.degree. C., the nitrogen dioxide containing atmosphere comprising at least about 10% by volume of nitrogen dioxide, the remainder of said atmosphere being water vapor and gas inert in the pyrolysis process.
