Abstract

Various (ZnO)₅In₂O₃ ceramics were fabricated by microwave heating. Density, XRD pattern and microstructure were examined, and those of the Al-doped (ZnO)₅In₂O₃ were almost the same as Al-free one. The highly textured (ZnO)₅In₂O₃ ceramic was also fabricated by reactive templated grain growth (RTGG) method. The electrical conductivity was not improved by Al-doping; however it was improved slightly by microwave heating compared with conventional heating and especially improved by texturing using RTGG method. On the other hand, the absolute Seebeck coefficient in microwave heating was improved about 25% by Al-doping. The maximum electric power factor of a textured specimen fabricated by RTGG method along the ab-plane showed 5.76×10^-4 WK^-2m^-1 (at 873K), which was attributed to high electrical conductivity.
