摘要
Macro-porous silicon carbide with high porosity around 70 vol%, comprising micrometer- sized spherical porosities and a relatively denser surface layer, was fabricated by a direct blowing and reaction bonding method. The macro-porous Si/phenolic composites with the denser surface layer were prepared through a one-pot process of blowing of novolac resin which changes to the phenolic resin by thermal curing to form macro-porous body and forming the denser surface layer. The composite was then converted into porous SiC by reaction bonding at 1450 degrees C under vacuum. It was found that the bending strength of the macro-porous silicon carbide increased by 30% due to the denser surface layer. This study proposed a novel fabrication method to provide macro-porous ceramics with high porosity and improved strength in simple one-pot process. (C) 2015 The Ceramic Society of Japan.
