20140185190 | METHOD FOR PRODUCING ELECTROLYTIC CAPACITORS FROM VALVE METAL POWDERS - A process for producing an anode for an electrolytic capacitor includes pressing a tantalum powder around a tantalum wire, a tantalum ribbon, or a tantalum sheet to form a pressed body. The pressed body is sintered to form a porous sintered body. The porous sintered body is cooled to form a cooled porous sintered body. The cooled porous sintered body is treated with at least one oxidant comprising at least one of a gaseous oxidant and a liquid oxidant to form a treated sintered body. The treated sintered body is anodically oxidized in an electrolyte to form a dielectric layer. | 07-03-2014 |
