摘要

Mullite bonded porous SiC ceramics were synthesized by infiltrating a SiC porous compact with a liquid precursor of mullite followed by sintering at 1300-1500 C in air. Different volume fractions (0-0.26%) of petroleum coke powder were used as pore former. SiC particles bonded by mullite and oxidation derived SiO_2 formed an interconnected porous network. Porosity varied in a range of 31-48 vol%. The flexural strength and the Young's modulus of the porous ceramics varied in the ranges of 19.3-43.8 MPa and 16.6-42.9 GPa respectively and the mechanical property-porosity relationship could be explained by the minimum solid area (MSA) model.
