摘　　要：从样品制备,烧结过程,纳米级Bi2O3添加量及电性能测试等方面介绍了掺杂纳米级Bi2O3对生产高热容量、大通流能量ZnO压敏电阻片性能的影响。试验结果表明:采用纳米级Bi2O3(x(Bi2O3)≥0.61%)代替普通Bi2O3,提高了老化及工频耐受性能,使烧成温度降低到1075℃,同时还降低了生产成本;并使电阻片的其它电气性能有所提高或保持原有的水平。The influence of dosing the nano-metric Bi2O3 to produce the high capacity and thermal-resistant ZnO varistor properties was introduced, from the aspects of sample preparation, sintering process, nano-metrie Bi2O3 dose and electrical testing etc.. The result shows that adopting the nano-metrie Bi2O3 instead of the normal Bi2O3, raise the aging and the power frequency withstand capability, makes the sintering temperature down to 1 075 ℃, lowered the production cost, and make other electricity performances of the resistor increase or maintained the original level.
