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