Previously synthesized nanocrystalline ZnO doped with cobalt and manganese, Bi2O3 and Sb2O3 were the precursors for high voltage varistors preparation. Varistor ceramics were sintered at 750 degrees C, 770 degrees C or 900 degrees C for 1 h. An amount of 30 mass% of secondary phases and sintering temperature of 770 degrees C were found to be optimal for obtaining varistor with prominent properties. Achieved density was 97% of the theoretical value. Post-sintering phase composition included ZnO, gamma-Bi2O3 and pyrochlore-type with Zn2Bi3Sb3O14 nominal formula. Fine grained microstructure was accompanied with good phase distribution and excellent electrical characteristics: extraordinary high breakdown field of 3200 V mm(-1), high nonlinearity coefficients of 71 and 51 in 0.1-1 and 1-10 mA cm(-2) current density ranges, respectively, and low leakage current of 7.7 mu A cm(-2).
