| Abstract: | The effect of B2O3 (B) and Al2O3 (Al) co-doping on electrical properties and microstructure of ZnO varistor ceramics are investigated. ZnO varistors doped with B and Al have excellent electrical properties such as low leakage current, high nonlinearity and low residual voltage. The electrical parameters of the ZnO varistor ceramics doped with 3.0% B and 0.015% Al(mole fraction)are as follows: breakdown voltage E1 mA=475 V/mm; leakage current JL=0.16 μA/cm2; nonlinear coefficient α=106; residual voltage ratio K=1.57. |
