Abstract：

Waste　aluminum　slag　and　oyster　shell　were　used　as　raw　materials　to　synthesize　calcium　hexaluminate　(CA　6　).　The　effects　of　different　source　materials　of　CaO　and　sintering　temperature　on　the　structures　and　properties　of　CA　6　were　investigated,　respectively.　The　results　show　that　compared　to　calcium　oxide,　oyster　shell　can　lower　the　formation　temperature　of　CA　6　,　hence　CA　6　can　be　detected　at　1300°C　by　using　oyster　shell　as　the　starting　raw　materials.　Increasing　the　sintering　temperature　can　promote　the　crystal　growth.　CA　6　crystals　show　typical　platelet　shape,　and　its　optimum　sintering　temperature　falls　in　the　1450~1550°C　region.　The　bulk　density　is　1.54~　1.83　g/cm　3　,　the　apparent　porosity　is　44.1~55.2%　and　the　flexural　strength　is　10.8~25.3　MPa.
