The hot-press sintering process of the thermoelectric materials ZnO was confirmed by use of the uniform experiment and the orthogonal experiment. The experimental results showed that because of the function of activate sintering in the hot-pressing experiment,the sintering temperature,pressing pressure and sintering time were decreased obviously, and the phase didn’t change. The thermoelectric property could be improved by the hot-pressing process because of having a lot of the small holes and loose construction in blank sample.
