Compact Al 2 O 3 ‐MgO·Al 2 O 3 ‐CaO·6Al 2 O 3 ( AMC ) composite was obtained by melting technology using industrial alumina, light‐burned magnesia, and quick lime as raw materials based on the Al 2 O 3 ‐MgO‐CaO ternary phase diagram. The results show that the phases of MgO·Al 2 O 3 and Al 2 O 3 are formed as the main framework with plate‐like CaO·6Al 2 O 3 crystals mainly discontinuously embedded in MgO·Al 2 O 3 . The bulk density of AMC composite is up to 3.42 g/cm 3 , equivalent to 90.5% of the theoretical density. The synthesized compact AMC composite in the work also exhibits better slag penetration resistance than the castable based on tabular corundum due to the formation of liquid phase.
