Abstract 0%—0.75% (mole fraction) SnO2 doped ZnBiMnNbO based varistor ceramics were produced by the traditional solid-state sintering procedure at low temperature of 875 ℃ for 3 h. The effect of SnO2 concentration variation on the microstructure and properties of the fabricated material was investigated by high precision scale, XRD, SEM, EDS and high-precision power-source unit. The result shows that the increment of SnO2 within the studied range can effectively improve the relative density and the formation of the Nb-containing Bi2Sn2O7 pyrochlore as the new secondary phase. The latter microstructural change leads the average grain size to decrease from 4.38 μm to 4.04 μm, and the breakdown voltage to increase from 727 V/mm to 1 024.37 V/mm. Meanwhile, the nonlinear coefficient increases from 32.37 to 52.64, and the leakage current density decreases from 13.5 μA/cm2 to 1.55 μA/cm2. The results of this study can provide a good reference to the development of high-voltage varistors with high nonlinearity at low cost.
