Abstract: A process for treating an impregnated electrolytic capacitor anode whereby the anode body is immersed in a liquid electrolytic solution and a voltage is applied to the anode body, whereby a current flows through and repairs flaw sites in the anode body. The liquid electrolytic solution includes an organic solvent comprising at least one of polyethylene glycol, polyethylene glycol monomethyl ether, and polyethylene glycol dimethyl ether. Atlernatively, the electolytic solution includes an organic solvent and an alkali metal phosphate salt. Preferably, the electrolytic solution contains both an alkali metal phosphate salt and an organic solvent comprising at least one of polyethylene glycol, polyethylene glycol monomethyl ether, and polyethylene glycol dimethyl ether.

Abstract: Organic acid-based binders are efficiently removed from powder metallurgy compacts, such as tantalum capacitor anode bodies, by immersion in a heated aqueous alkanolamine solution followed by rinsing in warm water. This method results in lower residual carbon and oxygen levels than are found with thermal binder removal methods.
