In　the　study,　sludge　from　the　aluminum　profile　factory　and　kaolin　were　used　as　the　raw　materials.　Through　adding　ZrO2　mineralizer　in　different　contents,　Al2-xZrx+yTi1-yO5　and　Al4.54Si1.46O9.73　and　solid　solution　multiphase　material　was　prepared　to　effectively　inhibit　the　decomposition　of　aluminum　titanate　solid　solution　and　optimize　high　temperature　property　of　the　multiphase　material.　With　XRD　and　SEM　means,　crystalline　structure　and　microstructure　of　each　sample　were　characterized,　and　properties　of　each　sample　were　tested.　According　to　experimental　results,　the　optimal　addition　amount　of　ZrO2　mineralizer　was　determined　to　be　1.5%.　Correspondingly,　contents　for　aluminum　titanate　solid　solution,　mullite　solid　solution　and　alpha-Al2O3　were　70.3%,　26.8%　and　2.9%　respectively,　bulk　density　was　3.20　g/cm(3),　degree　of　porosity　was　5.57%,　water　absorption　rate　was　1.74%,　and　the　once　thermal　shock　rupture　strength　retention　rate　was　90.52%.
