| Abstract Scope |
Silicon (Si) and carbon (C) powders were used as the starting materials for the fabrication of porous SiC ceramics. During the heating, the Si powder was reacted with C powder and synthesized to β-SiC at ~1500℃ in Ar atmosphere. When the formed β-SiC particles transformed to α-SiC at 2100℃, rapid grain growth of α-SiC was consumed the β-matrix SiC particles and porous structure with huge elongated plate-like grain was formed. The effect of initial composition on the microstructure formation of porous SiC ceramics and their mechanical properties were investigated and discussed. |
