| 摘 要： | 研究了在烧结过程中，烧结温度与等温烧结时间对ＺｎＯ晶粒中次晶界的影响及次晶界对ＺｎＯ压敏陶瓷电性能的作用，结果发现随烧结温度升高、等温烧结时间延长，次晶界趋于消失，次晶界的存在将增大ＺｎＯ晶粒的电阻率、削弱ＺｎＯ压敏陶瓷的脉冲能量吸收能力。

| Abstract: | The effects of sintering temperature and soak time on the sub- grainboundaries in ZnOgrains and the effects of sub-grainboundaries on the electrical characteristics of ZnO varistorceramics were investigated.It is found that sub-grainboundaries tend to disappear with theincreasing of sintering temperature and soak time,Sub-grainboundaries can not only raise re-sistivity of ZnO grains,but also deteriorate the pulse energy absorption capability of ZnOvaristor ceramics. |
