We　aim　in　this　research　at　synthesizing　high-purity　aluminium　titanate　with　sludge　from　the　aluminium　profile　factory　by　shock　cooling　method,　and　mainly　discuss　the　effect　of　calcining　reaction　temperature　and　holding　time　on　crystalline,　microstructure　and　content　of　aluminum　titanate　materials　to　determine　the　preferred　calcining　temperature　and　holding　time.　XRD　and　SEM　methods　were　utilized　to　characterize　the　crystalline　and　microstructure　of　each　specimen,　Rietveld　Quantification　software　was　used　for　the　determination　of　different　crystalline　contents　of　specimens,　and　Philips　plus　software　was　applied　to　determine　the　cell　parameters　of　aluminium　titanate　in　different　specimens.　According　to　the　experimental　results,　preferred　calcining　temperature　is　determined　as　1400　degrees　C　and　preferred　holding　time　is　2　h,　at　which　the　grains　of　aluminum　titanate　grow　completely　and　the　purity　of　aluminum　titanate　is　97.2　wt%.
