| 中文摘要 | Ca, Ta-doped TiO2 varistors with high nonlinear coefficients are obtained by a ceramic sintering. The nonlinear electrical and dielectric properties of the samples doped with 0.5mol% Ca and various concentrations of Ta (0.05 similar to2.0mol%) were investigated. The samples sintered at 1350 degreesC have nonlinear coefficients of alpha = 5.1 similar to42.1 and high relative dielectric constants approach 10(5). The effects of Ta-doping on the nonlinear and dielectric properties of the Ca, Ta-doped TiO2 varistors are studied in greater detail. When the concentration of Ta is 0.5mol%, the sample possesses the highest nonlinear coefficient and a comparatively lower dielectric constant. The effects of Ta and the nonlinear electrical behavior of the TiO2 system are explained by analogy to a grain-boundary atomic defect model. |
