Abstract The porous mullite ceramics doped with such metal oxides as ZrO2, WO3 and MgO in quantity of 5 wt% were prepared by slip casting method. The mullite phase was the main and dominant phase of ZrO2-, WO3- and MgO-doped samples, which were sintered at the temperatures of 1650oC, 1500oC, respectively. The ZrO2, WO3 and MgO had the positive effect on the increase of porosity and decrease of thermal conductivity of porous mullite ceramics and the degree of this effect was in the order of ZrO2<MgO<WO3.
