Effect of Al(OH)3 Addition on the Properties of SiC/Al2O3 Composite Porous Ceramics

Article Preview

Abstract:

SiC/Al2O3 composite porous ceramics were prepared by an in situ reaction bonding technique and sintering in air with SiC and A1(OH)3 as starting materials. The pores in the ceramics were formed by stacking particles of SiC and A12O3. The surface of SiC was oxidized to SiO2 at high temperature. With further increasing the temperature, SiO2 reacted with A12O3 to form mullite. The reaction bonding characteristics, phase composition, and mechanical strength as well as microstructure of porous SiC ceramics were investigated.
