Hierarchical pore structure mullite ceramics with macro- and meso-pores were prepared by a foam-gelcasting method and a pore-forming agent method using SiC and CaCO3 as additives. The effect of SiC amount on the flexural strength, compressive strength and thermal conductivities of porous ceramics was also investigated. The results show that porous mullite ceramics with a lot of close pores can be fabricated via the method with mullite powder as a raw material and CaCO3 and SiC (0-8% (mass fraction)) as additives. The as-synthesized porous mullite ceramic prepared with 4% (mass fraction) SiC has 69.9% porosity and a lowest thermal-conductivity.
