															Abstract:  CaAl12 O19 /(MgAl2 O4 -Al2 O3 ) composite ceramics were prepared by liquid infiltration. The effects of different molar ratios (n (α-Al2 O3 ):n (MgO)=1:1, 2:1, 3:1, 4:1) of raw materials on the phase composition, microstructure and properties of composite ceramics were studied. The results showed that MgAl2 O4  phases were confirmed as magnesia-rich or alumina-rich nonstoichiometric spinel. When the content of Al2 O3  was insufficient, the Ca12 Al14 O33  and CaAl4 O7  phase were generated. Compared with the uninfiltrated samples, the low melting point Ca12 -Al14 O33  might promote the growth of MgAl2 O4  grains. Although the formation of CaAl12 O19  with plate-like morphology reduced the bulk density of samples, the strength increased instead, playing a role of strengthening and toughening. As the content of Al2 O3  increased, the bulk density and flexural strength of the samples increased gradually.
