发明名称 Method for making anodes for electrolytic capacitor with high volumetric efficiency
摘要 A method for manufacturing valve metal anodes of electrolytic capacitors by deoxidizing the anodes using Mg vapor in a deoxidizing furnace, removing the anodes from deoxidizing furnace, placing them in sintering furnace, sintering at temperature lower than the temperature conventionally used for sintering in vacuum, and leaching of Mg oxide off the anode surface. The process limits free oxygen and improves morphology of valve metal anodes, which results in improved performance of electrolytic capacitors with these anodes. The process does not require any special equipment or maintenance operations and, thereby, is highly productive due to performing deoxidizing and sintering separately in traditional deoxidizing and sintering furnaces.
