High-purity　aluminum　titanate　was　synthesized　via　a　water　quenching　method　with　waste-residue　in　the　aluminum　factory　and　industrial　TiO2　as　the　main　raw　materials,　which　belongs　to　the　comprehensive　utilization　of　solid　wastes.　Compared　with　the　conventional　method,　it　can　reduce　synthesis　temperature,　effectively　inhibit　decomposition　and　raise　the　content　of　AT;　the　addition　of　tiny　silicon　powder　can　improve　the　sintering　and　optimize　the　properties　of　AT.　The　crystalline　phase　structure　and　microstructure　of　each　sample　were　characterized　with　XRD　and　SEM　methods;　the　content　of　each　crystalline　phase　in　each　sample　was　confirmed　with　Rietveld　Quantification　method;　the　properties　of　each　sample　were　also　tested.　The　experimental　results　showed　that　No.　4　is　the　optimum　specimen,　with　the　corresponding　mass　ratio　of　Al2O3/TiO2　to　be　1.27　and　the　content　of　AT　of　97.2　wt%.　The　addition　of　optimum　tiny　silicon　powder　is　confirmed　to　be　8wt%;　its　corresponding　bulk　density　is　2.63　g/cm(3),　bending　strength　is　46.34　MPa,　and　the　retention　of　one　thermal　vibration　bending　strength　is　71.5%.
