Abstract
A process for making a valve metal material useful for forming electrolytic devices comprising the steps of: establishing multiple tantalum or niobium components in a billet of a ductile material; working the billet to a series of reduction steps to form said tantalum or niobium components into elongated elements; cutting the resulting elongated elements and leaching the ductile metal from the elements; washing and mixing the cut elements; and forming the cut elements into a sheet. The resulting sheet may be formed into anodes and cathodes and assembled to form a wet electrolytic capacitor.
