N2 - Al, Ga dually-doped ZnO was prepared by spark plasma sintering with different sintering temperatures. The microstructural evolution and thermoelectric properties of the samples were investigated in detail. The samples with a sintering temperature above 1223K obtained higher relative densities and better electrical properties compared with the sample sintered at 1073K. These results were supported by solid-state-reaction completion rate which suggested that the sintering temperature above 1223K would be preferable for the complete solid state reaction of the samples. The sintering mechanism of ZnO particles and microstructure evolutions at different sintering temperatures were investigated by the simulation of the self-Joule-heating effect of the individual particles.
