AbstractPorous silicon nitride ceramics were directly prepared by self-propagating high temperature synthesis (SHS). The effects of Si3N4 diluent and Y2O3 sintering additive on the phase composition and microstructure were investigated. The XRD patterns and SEM microstructures proved the sample with 63 wt% Si3N4 diluent could provide appropriate temperature, reaction time and porosity for the fabrication of elongated beta-Si3N4 porous ceramics. A porosity of 40%-47% and a flexural strength of 118-216 MPa were obtained after SHS with different Y2O3 content. Besides, the excellent thermal shock resistance of Si3N4 assured that strength retention keeps stable in the temperature difference (Delta T) of 800 degrees C.
