• In this work, the microstructure, thermal and electric conductivity properties of near-zero thermal expansion ZrW_2O_8/ZrO_2 and Al_2O_3 added ZrW_2O_8/ZrO_2 composites were studied. Both the two composites exhibit very low thermal conductivity and the thermal conductivity decreases slightly as the temperature increases. The electric conductivity of the two composites increases with the increasing of the measurement temperature. The Al_2O_3 added ZrW_2O_8/ZrO_2 composite has higher thermal and electric conductivity than ZrW_2O_8/ZrO_2 composite. The most important factor which causes the difference of the thermal and electric conductivity of the composites is the porosity.
