摘要
介绍了氧化锌(ZnO)低压压敏电阻研究的必要性。分析了TiO2添加剂促进ZnO压敏电阻晶粒长大的过程和机制;探讨了ZnO压敏电阻低压化机理。宏观电性能测试表明:ZnO压敏电阻中TiO2添加剂的加入,可很好地实现ZnO压敏电阻低压化的目的。
Necessity of the research on low-voltage ZnO varistor was introduced. Then, process and mechanism of grain growth of ZnO varislor with TiO2 addition were analyzed. In the end, mechanism of low-voltage ZnO varistor was probed. Macroscopic electric test shows that adding the TiO2 additive into the ZnO varistor properly can realize the aim making the ZnO varistor to be using in low voltage range.
