摘要
简要回顾了ZnO压敏电阻器的历史 ,阐述了ZnO压敏电阻器的性能以及当前基础性研究的现状 ,并对其发展进行了展望。研究了Bi2 O3 和TiO2 的掺杂对低压ZnO压敏电阻性能和微观结构的影响规律 ,从理论上分析了Bi2 O3 和TiO2 添加剂的作用机理。为ZnO压敏电阻的低压化提供了理论依据和方法。
In this paper,the history,properties and the recent technological status of ZnO varistor were reviewed and its development was discussed at the same time.After the two additives are classified by their functions,the effecting mechanism of Bi_2O_3 and TiO_2 additives were studied theoretically.It provided an effective method and rational basis for studying low-voltage ZnO varistor.
