Notes:
Mullite is a versatile material used in traditional and advanced ceramic, due to lowthermal expansion, high thermal shock and creep resistance. The production of waste from oreindustry is a problem that is increasing nowadays. The kaolin processing industry produces residuerich in Al2O3 and SiO2. These oxides are good precursors to produce mullite. The aim of this workis to use the residue from kaolin industry to produce mullite ceramic bodies. It was studied alumina,clay and residue from kaolin processing as raw materials. The material was dried and pressing inuniaxial press (30MPa). The samples were sintered at temperatures of 1450oC, 1500oC, 1550oC and1600oC. The ceramic bodies were characterized by X-ray diffraction. The density was measured byArchimedes method and the flexural strength by the three point bending technique. The resultsshowed that is possible to produce mullite with high amount of waste from kaolin processing
