Sialon-based ceramics have been synthesized from aluminum dross, which is discharged in aluminum manufacturing, by the nitriding combustion mode of Self-Propagating High Temperature Synthesis (SHS). The Al dross used consisted of mainly AlN, Al_2O_3, and Al. It was blended with the combustion agents of reclaimed Si, and electrically ignited in a pressurized nitrogen atmosphere of 1.0MPa. The mixtures were converted to sialon phases with a small quantity of unreacted Si. The product powders were sintered at 1500℃ in a nitrogen atmosphere. When the sintered product was heated in air at 1300℃, a mullite layer was formed at the surface with a thickness of 10-15μm, which could improve significantly the oxidation and corrosion resistance.
