Manufacturing Technology for Niobium Oxide Electrolytic Capacitor and Several Correlative Mechanisms

摘要：

　　Methods of manufacturing Niobium oxide electrolytic capacitor were studied in this work.Some phenomena were found and the reasons or mechanisms were studied by using SEM(scanning electron microscope),EDS.In experiment,comparing with the type 6.3V/47μF tantalum capacitor,NbO powder was pressed to pellet as the capacitor anode,then the NbO capacitor was manufactured through the following processes:sintering,welding,anode oxidation,MnO2 decomposition and cathode coating.Its capacitance,leakage current,ESR(equivalent series resistance) and tgδ were measured and compared with that of the simily type of tantalum capacitor,and the suitable technical parameters were chosen.
