    Alumina/calcium-hexaluminate composites was synthesized through reaction sintering of alumina and bauxite reducing slag. The alumina/calcium-hexaluminate composites is mainly composed of 6.57% ¦A-Al2O3, 23.92% anorthite, and 57.13% calcium-hexaluminate. Gehlenite phase was effectively transformed to anorthite and calcium-hexaluminate through high-temperature reaction sintering under a weak oxidizing atmosphere at 1400 ¡aC for 4 h. SEM and EDS analysis indicated that black and needle-shaped Al2O3, rhombic or irregular polygonal-shaped hercynite and glassy-phase gehlenite disappeared after the reaction sintering. The light gray and flaky hexagon crystals of calcium-hexaluminate (10 ¦Im) and the grainy particles of Al2O3 (2¨C7 ¦Im) were also observed in the alumina/calcium-hexaluminate composites. The gray crystals of anorthite act as binding phase and are distributed around calcium-hexaluminate and Al2O3. Alumina/calcium-hexaluminate composites present high refractoriness and using temperature, which are 1650 ¡aC and 1450 ¡aC, respectively. Reaction sintering between alumina and bauxite reducing slag is a feasible method for the synthesis of alumina/calcium-hexaluminate composites.
