In order to obtain mullite/zirconia composites, mixtures of aluminum dross and zircon were sintered. Aluminum dross was collected and purified by a milling, sieving and washing process. Stoichiometric mixtures of aluminum dross and zircon were sintered at several temperatures (1400, 1450 and 1500 degrees C) forseveral periods of time (2,4 and 6 h). After the purifying treatment the dross contained mainly Al(2)O(3), AlN, MgAl(2)O(4), SiO(2) and metallic Al. A homogeneous mullite matrix with small zirconia particles was obtained by sintering the aluminum dross-zircon samples at 1500 degrees C for 6 h. (C) 2008 Elsevier Ltd and Techna Group S.r.I.
