ZnO varistors doped with Bi2O3, Sb2O3, CoO, MnO2 and Cr2O3 were prepared separately by
two mixing processes: conventional and masterbatching mixed-oxide process method.
After the mixing process, the ZnO-based varistor powders were milled using planetary
ball mill at 200, 300, 400 and 500 rpm. Particle size analysis and XRD analysis were
used to study the differences after milling process in ZnO-based varistor powder. The
particle sizes of varistor powder were reduced and new compound encountered after
milling process.
