INVESTIGATION OF COLUMBIUM AS AN ELECTROLYTIC CAPACITOR ANODE, PART II,

Abstract

Anodic oxide films that have excellent wet electrical properties can be electrolytically formed on columbium foils and on properly processed sintered columbium pellets. During the fabrication of formed columbium anodes into solid electrolytic capacitors, the temperature used for deposition of the solid manganese dioxide electrolyte causes consid erable degradation of the electrical properties. Effects of this degradation can only be partially restored by reformation and aging processes. The temperature sensitivity of the oxide film is a significant determining factor for the properties of solid columbium electrolytic capacitors. Further investigations are indicated to develop (a) sintered columbium anodes of higher purity and optimum design, (b) optimum techniques for the formation of the anodes, and (c) optimum techniques for processing the formed anodes into solid electrolytic capacitors.
