Method of manufacturing a sintered anode unit for a solid electrolytic capacitor, continuous sintering apparatus and method of manufacturing secondary particles of a valve-action metal powder |
摘要 |
<p>A method of manufacturing a sintered anode unit for a solid electrolytic capacitor is provided. According to this method, a press-molded or compacted pellet of a valve-action metal powder is sintered at a predetermined high temperature and in a predetermined primary vacuum. The pellet is naturally cooled in this primary vacuum, and is cooled by force cooling in an inert gas atmosphere. Thereafter, the sintered pellet is subjected to a repeated cycle processing of vacuum, atmospheric leakage, and vacuum in a gradual-oxidizing chamber. The atmospheric leakage level is increased step by step to set the vacuum level in the gradual-oxidizing chamber to the atmospheric pressure. Then, the sintered pellet having the restricted content of oxygen is taken out from the gradual-oxidizing chamber into the atmosphere.</p> |
