Abstract Zn_0.98-xAl_0.02W_xO (x=0, 0.005, 0.01, 0.02) precursor powders were synthesized via a sol-gel method and their ceramics were prepared for 5 h at 1 400 ℃ in N₂ atmosphere. The phase composition and microstructure of the samples were characterized by XRD and SEM. The effects of W doping on the thermoelectric properties of Zn_0.98Al_0.02O ceramics were investigated. The absolute value of the Seebeck coefficient of the material decreased first and then increased with the increase of the amount of W, and the conductivity showed an opposite trend. The sample with x=0.005 showed the highest power factor of 3.6×10^-4 W/(m·K) at 773 K, which is twice higher than Zn_0.98Al_0.02O. In addition, the doping of W effectively reduced the thermal conductivity. The highest ZT of 0.03 was obtained by x=0.005 sample at 773 K, which was 2.3 times higher than Zn_0.98Al_0.02O.

Key words： Zn_0.98Al_0.02O ceramics thermoelectric property zinc oxide W doping
