| 摘 要： | 以3Y2O3—ZrO2纳米粉和ZnO，A12O3纳米粉为原料，采用交流阻抗谱技术对掺少量ZnO和A12O3的3Y2O3—ZrO2烧结陶瓷进行电性能研究。研究表明：少量纳米ZnO掺杂降低了3Y2O3—ZrO2的电导率，但随着掺人量的增加，电导率开始回升。在ZnO掺杂样品中加入少量纳米A12O3进行复合第二相掺杂，结果提高了3Y2O3—ZrO2材料的电导率。同时少量A12O3的掺人降低了晶粒电导活化能，使得晶粒电导率增加。 |

| Abstract: | With adding of nano-Al 2O 3 and nano-ZnO,the conductivity of 3Y 2O 3-ZrO 2 ceramics were studied with a.c.impedance spectroscopy measurement.The results show that the conductivity of 3Y 2O 3-ZrO 2 decreased with a small addition of nano-ZnO.But,with the increasing of nano-ZnO,the conductivity recovered.When a small content of nano-Al 2O 3 were adulterated in ZnO-doped smaples,it was found that nano-Al 2O 3 adulteration enhanced the conductivity of samples.The reduction of activation energy and increase of intragranular conductivity were observed when doped with 1%(in mass)nano-Al-2O-3. |
