摘要：
A wet chemical method has been applied to synthesize zinc oxide varistor in order to obtain chemically pure and homogeneous product. Efficient yield was attained for precursors by a precipitation method using zinc acetate as a starting material with praseodymium oxide and cobalt chloride as additives. The calcination process, crystalline size of zinc oxide, additives distribution and voltage-current curve were characterized for the samples, which were prepared by a wet chemical method with or without calcination, and by a ball-mill method for comparison.
