Abstract Full text About this article

SiC honeycomb ceramics with parallel channels and macroporous walls were prepared by combining extrusion molding with pressureless sintering technology in the presence of starch. The extrusion molding constructed honeycomb structure with parallel channels, while the starch formed spherical macropores on the channel walls. The density and bending strength of SiC honeycomb ceramics decreased with the increase of starch content, while the phase compositions did not vary with the starch content. The control in starch addition could adjust the pore structures on the channel walls of SiC honeycomb ceramics.
