摘　　要：为了确定氧化锌压敏陶瓷常规烧结的最佳工艺,采用正交实验法,综合考虑升温速度、烧结温度、保温时间、降温速度这四个因素对氧化锌压敏陶瓷电性能和密度的影响。经论证,最佳的氧化锌压敏陶瓷烧结工艺条件和各影响因素主次顺序为烧结温度1150℃,保温时间4 h,降温速度60℃/h,升温速度30℃/h。经实验验证,应用该工艺条件烧制而成的氧化锌压敏陶瓷的各项指标均优于各个实验样本。Zinc oxide varistor ceramics are widely used in the manufacturing of arresters,surge absorbers and other devices for their excellent electrical properties.The work is aimed to determine the optimal process for the conventional sintering of zinc oxide varistor ceramics.In this paper,the orthogonal experiment method was employed.The effects of four factors,such as heating rate,sintering temperature,holding time and cooling rate,on the electrical properties and density of zinc oxide varistor ceramics were considered by orthogonal experiment.After demonstration,optimal sintering process and primary and secondary order of influencing factors of ZnO varistor ceramics were sintering temperature 1150℃,holding time 4 h and cooling rate 60℃/h,heating rate 30℃/h.Through the verification experiment,the indexes of the ZnO varistor ceramics fired by the process conditions are better than those of the samples,which verifies the reliability of the conclusions of this paper.
