Abstract

Al₂O₃-doped ZnO ceramics were prepared via chemical co-precipitation processing. Zinc acetate, ammonia and Al₂O ₃ powders are used as starting materials. Scanning electron microscopy (SEM) observations reveal that the doping of Al₂O ₃ has an obvious influence on the microstructure of ZnO ceramics. Ordinary cold pressing and cold isostatic pressing (CIP) were used to prepare green compacts. The thermal conductivity and electrical conductivity of the Al₂O₃-doped ZnO ceramics were measured as a function of the testing temperature (0-900°C). Doping of Al₂O₃ is beneficial to improve thermoelectric (TE) properties of ZnO ceramics. CIP can also improve TE properties of Al₂O₃-doped ZnO ceramics.
