Ca, Ta)-doped TiO 2 varistors with high nonlinear coefficients were obtained by ceramic sintering process. The nonlinear electrical and dielectric properties of the samples doped with 1.0 mol% Ca and different concentrations of Ta (0.05-2.0 mol%) were investigated. Especially, the effects of Ta dopa
