摘　　要：研究了Ｂｉ、Ｓｂ、Ｍｎ、Ｎｉ及Ａｌ作为添加剂对直流氧化锌电阻片性能的影响，由于直流与交流导电机理的不同，所进行的热处理工艺也不同，热处理后对电阻片非线性的比较及预掺铝工艺试验可知，工艺因素即工艺方法与参数对电阻片的影响远大于添加剂量在５％以内变化的影响，并进行了批量试验。The effect of additive amount such as Bi、 Sb、Mn、 Ni and Al on dc ZnO varistor properties has been studied The different couduction mechanism of ac and dc varistors induces the different and annealing procedure for ac and dc varistors Comparison of nonlinearity behaviours of varistors proceeded with different annealing procedure nonlinearity and alumina pro dosing experiments show a greater effect of processing procedure and parameters on varistor performance as compared with variation of additive amount within ±5% A batch production has confirmed the conclusion
