摘要：

The porous SiC-cordierite ceramics were prepared from SiC, calcined kaolin, talc, aluminum hydroxide, and graphite as pore-forming. The influence of pore-forming agent contents and sintering temperatures on the porosity and flexural strength of porous SiC-cordierite ceramics were investigated. The grain phases and the fracture surface micrograph were analyzed with XRD and SEM, respectively. The results show that the sample sintered at 1350 degrees C for 3h with 15% graphite as the pore-forming agent exhibits the most excellent properties: flexural strength of 63.74MPa was achieved at a porosity of 31.80%.
