籽晶法制备低压ZnO压敏电阻器

研究了ＺｎＯ籽晶粒度、掺入量及其制备方法对压敏电压的影响。实验结果表明：掺入适量粒度合适的籽晶，勿需在高温下长时间烧结，也可制成压敏电压较低，漏电流较小的ＺｎＯ压敏电阻器。

Preparation of low voltage ZnO varistors with seed crystal

豹he effect of ZnO seed size, additive quantity and preparation methods on the voltage is studied The result shows that the ZnO varistor of low voltage and low leakage current can be obtained by adding appropriate seeds without long and high temperature sintering(6 refs)
