Abstract
Samples ofAl dross collected fromthree different aluminumfoundrieswere processed and characterized. A mixture of the three processed dross containsmainlyAl 2O3,Al, SiO2,MgAl2O4 andAlN. This drossmixturewas used as raw material to obtain high-grade ceramics composites such as SiAlON and mullite-zirconia. X-ray diffraction and electronmicroscopy analysis of the products obtained showed that SiAlON and mullite-zirconia composites were formed.
