Abstract: Al₂O₃/5%Mullite compos ite was synthes ized by us ing reacting s intering of Al₂O₃/0.78%SiC at 1600°C for 2 h in air. The compos ite exhibited quite low mechanical properties . There were two kinds of mullite in the compos ite, i.e., 3Al₂O₃·2SiO₂ and Al_5.65Si_0.35O_9.175.

Keywords: compos ite, ceramics , reacting s intering, micros tructure
