ABSTRACT:
A protective layer containing polytetrafluoroethylene (PTFE) is provided over the riser of an anode having a porous film-forming metal anode body to render the riser non-wetting to a solution of manganese nitrate and thereby help prevent the formation of MnO.sub.2 on the riser during the subsequent pyrolysis step in the process of making a capacitor. The protective layer also helps to prevent mechanical damage to the anode during assembly of the capacitor. The protective layer over the anode riser may be applied by means such as dipping a wetted anode in a suspension containing particulate PTFE or by masking the anode body with a liquid and then spraying the riser with binderless material containing PTFE. The preferred embodiment employs high pressure spraying of the material containing PTFE over the anode riser.
