Abstract
An Al2O3/5 vol mullite composite was synthesized by using reaction sintering of Al2O3/078 wt SiC at 1600 °C for 2 h in air The phase analysis of the Al2O3/mullite composite was carried out using Xray diffraction XRD There were two kinds of mullite in alumina/mullite composite namely 3Al2O3·2SiO2 and Al565Si035O9175 The microstructure of the Al2O3/mullite composite was investigated using scanning electron microscope SEM and transmission electron microscope TEM The mechanical properties such as Young’s modulus Poisson’s ratio hardness toughness and strength of the Al2O3/mullite composite were investigated The influence of mullite on the composite is discussed
