High Porosity SiC Ceramics with a Narrow Pore Size Distribution

摘要：

　　Using the coat mix process,porous SiC ceramics are fabricated using commercially available silicon powders and phenolic resin as the starting materials.The phase composition,morphology,pore size and pore size distribution of the obtained products are characterized by X-ray diffraction,scanning electron microscopy and mercury intrusion porosimeter.The results show that high porosity SiC ceramics with a narrow pore size distribution can be fabricated at 1500℃ in vacuum by the coat mix process.The open pore porosity can reach up to 60%.The pore size varies in the range of 1-6 μm.
