AbstractPowders used to produce zinc oxide ceramic varistors were prepared, by wet chemical route. SEM and XRD were used to characterize the powder properties and the microstructure of the varistors. It was shown that nearly spherical ZnO powders could obtain varistors of homogenous microstructure and help to improve its nonlinear coefficient in large current case and current surge capability. The effects of preparation technique of ZnO powders doped with Co,Mn and the additive powders on varistors were also studied. The microstructure of varistors made from the powders prepared by co-precipitation is more homogeneous and the nonlinear coefficient about 50 and high breakdown fields and large surge capability were achieved.
