摘　　要：本文研究了分别掺杂微量Fe2O3杂质对ZnO压敏陶瓷的压敏特性的影响。研究结果表明:随Fe2O3掺杂量的增加,ZnO压敏陶瓷的压敏电压V1 mA和非线性系数先下降,后升高,最小值出现在Fe2O3摩尔掺杂量为1.00%;并从理论上详细地探讨了产生这些影响的原因。The effects of Fe2O3 doping content on properties of ZnO varistor ceramics were studied. The experimental result showed that with the increase of the addition of Fe2O3 into ZnO varistor ceramic, the varistor voltage V1 mA and the non -linear coefficient decreased firstly and then increased, the minimum value was found at the Fe2O3 content of 1.00% （molar volume）, and the reasons for these effects were discussed theoretically in detail.
