The mechanical and thermal properties of porous ceramics with the controlled pore design were investigated through experiments and numerical analysis. Porous alumina ceramics containing well-defined pore shape, size and distribution were prepared by incorporation of fugitive additives into alumina. Processing variables provide various microstructure and the amount of porosity as well. Young's modulus and thermal conductivity were evaluated by resonant frequency and laser flash method, respectively. Elasticity changes with different pore structure were calculated by using finite element analysis (FEA) and compared with experimental data. Finite element analysis was confirmed as a useful tool to simulate the effect of pore structure on the mechanical and thermal properties of porous ceramics. The design parameter of pore structure of porous ceramics will be discussed based on the result of analysis.
