| Abstract: | Based on previous work,the effect of factors in preparing zinc oxide powders from five components by coprecipitation-coating doping process on mole ratio percent of components,particle size distribution,particle morphology and electric performance has been studied in this paper.The optimum process parameters have been obtained.Based on the comparision of electric performance of the varistors prepared by three different methods,a process for manufacturing zinc oxide varistor has been established. |
