| 摘 要： | 通过研究微米粉体、纳米粉体和纳米胶体TiO2掺杂的ZnO压敏电阻的电性能,发现纳米胶体TiO2掺杂的ZnO压敏电阻具有较低的电压梯度和漏电流,而非线性系数较高.对电性能结果的分析表明:在ZnO-Bi2O3-TiO2低压压敏电阻中,晶界击穿电压不是一个固定值;漏电流中的线性分量对TiO2掺杂的ZnO压敏电阻电学性能影响很大. |

| Abstract: | The electric properties of ZnO varistors doped with TiO2 in different forms including micrometer powder, nanometer powder and nanometer sol were presented. The results show that lower breakdown voltage, leakage current and better nonlinear coefficient are obtained for the sample doped with nano-sol TiO2. The breakdown voltage of grain boundary is not a constant for the ZnO-Bi2O3-TiO2 low-voltage varistors. And the linear part of the leakage current has great effects on the electric properties of the samples doped with TiO2. |
| Keywords: | zinc oxide varistors nanometer sol titania additive electric properties |
