Abstract

Mullite bonded porous SiC ceramics were synthesized by infiltrating a powder compact of SiC and Y2O3 with a liquid precursor of mullite which on subsequent heat treatment at 1300-1500 degrees C produced mullite bonded porous SiC ceramics. The effect of Y2O3 content and sintering temperature on phase composition, microstructure, oxidation degree of SiC, flexural strength, porosity and pore size distribution were studied. Due to enhance oxidation and well developed neck formation by the addition of Y2O3 a high strength 49 MPa was achieved for the porous mullite bonded SiC ceramics with porosity 28 vol %.
