| Abstract: | ZnO varistor was prepared with different sintering temperature.The microstructure was analyzed by SEM and the effect of sintering temperature on electrical properties of ZnO varistor was investigated.The results show that ZnO varistor with sintering temperature 1 020 ℃ and holding for 90 min can obtain better nonlinear electrical properties,the value of gradient voltage reaches 408 V/mm,while the leakage current and nonlinear coefficient are 1.8 μA and 37,respectively;the value of gradient voltage reaches 475 V/mm when sintering temperature is 1 000 ℃. |
