TiO2掺杂对低压ZnO压敏电阻性能的影响
The Effects of TiO2 Content and Process on the Electrical Properties in TiO2-doped ZnO Varistors
【摘要】 研究了 Ti O2 掺杂量及制备工艺对 Zn O压敏电阻性能的影响。Ti O2 掺杂超过一定量时 ,压敏场强就不再降低 ,而非线性系数却一直下降 ,漏流迅速增大 ,使性能劣化。因此 ,要控制 Ti O2 掺杂量在适当范围内。粉料煅烧温度和烧成温度的高低也直接影响 Zn O压敏电阻性能。
【Abstract】 The effects of content of TiO 2 dopant and process on the microstructure and electrical properties were studied.TiO 2 dopant can drastically decrease the breakdown field of the ZnO varistor,but then has little effect on the breakdown field when it surpass 0 3%.Furthmore,the electrical property of ZnO varistor was adjusted by pre firing temperature and sintering temperature.
