Characterization of industrial incinerating wastes have been conducted by Thermogravimetric Analysis (TGA), Scanning Electron Microprobe (SEMP), X-Ray Diffraction (XRD) and Scanning Electron Microscopy (SEM). During the treatment of incinerating residues with free temperature increase (20-1.000 °C) in air, some weight losses determinations have been observed, indicating an incompleted incineration. XRD characterization reveáis the presence of poorly crystallized phases in these slags. Data from SEMP were statistically treated with the purpose to determine the pseudostructure of these solids. This allows estimation of the possible association of elements in the amorphous solid, and, consequently, to forsee their adequated treatment.
