<p>A process for producing anodes includes providing a foil comprising tantalum or niobium. A surface of the foil is oxidized so as to form oxides on the foil surface. The foil is heated so that the oxides formed on the foil surface diffuse into the foil. A paste comprising a powder selected from the group consisting of a tantalum powder, a niobium powder, a niobium oxide powder and mixtures thereof is applied to the foil. The foil with the applied paste is sintered.</p> |
