采用ZnO掺杂和与ZnO直接混合两种方式分别制备10 wt%BaZr0.9Y0.1O2.95-90 wt%BaCe0.86Y0.1Zn0.04O2.91(BZY-BCYZn)和10wt%BaZr0.9Y0.1O2.95-90wt%BaCe0.9Y0.1O2.95-ZnO(BZY-BCY-ZnO)复相电解质材料,比较ZnO的不同引入方式对BZY-BCY复相电解质烧结和电性能的影响。结果表明:ZnO掺杂制备的BZYBCYZn电解质材料具有更加致密的显微结构和更高的电导率,在1350℃烧结5h基本达到致密,在600℃湿润Ar条件下电导率达到7.3mS/cm。
ZnO doped and ZnO mixed directly prepared two kinds of 10 wt% BaZr0.9Y0.1O2.95-90 wt% BaCe0.86Y0.1Zn0.04O2.91 (BZY-BCYZn) and 10wt% BaZr0.9Y0.1O2 The effect of different introduction modes of ZnO on the sintering and electrical properties of BZY-BCY composite electrolytes was investigated. The results show that the BZYBCYZn electrolyte prepared by ZnO doping has a denser microstructure and higher conductivity. After sintering at 1350 ℃ for 5h, the BZYBCYZn electrolyte has a compact structure and conductivity of 7.3mS / cm at 600 ℃.
