| Abstract: | The (Ba0.960Sr0.040Ca0.060)Ti1.044O3+x system PTC component of over-current protection for communication equipment was prepared by electroceramic process. The effects of special heat treatment and chemical treatment on its PTC characteristics were investigated by SEM and failure mode tester etc.. At the same time, aluminum electrode was susbstituted successfully for silver-zinc ohmic electrode. The results show that the PTC components prepared by this process demonstrate the desirable properties, including ... |
