Paper Abstract

The regularity of the effect of Bi4Ti3O12-doped on the electrical properties of low voltage ZnO varistor was studied. The effects of annealing temperature on the electric characteristics of samples were discussed and the mechanism of Bi4Ti3O12-doped was analyzed. It is found that the electric properties of Bi4Ti3O12- doped samples are better than Bi2O3- and TiO2- doped samples, and the samples of Bi4Ti3O12- doped can overcome the weakness of Bi2O3 volatilization at high temperature. For 0.5mol% Bi4Ti3O12-doped samples sintered at 1280 degree(s)C for 2h, the electric properties were that V1mA equals 45v, (alpha) > 32, IL < 3 (mu) A.
