Abstract Scope |
Three types of glassy wastes have been investigated: bottle glass, glass-polishing sludge, and glass packaging. The waste material was crushed and screened at 325 mesh. X-ray fluorescence (XRF), differential scanning calorimetry(DSC), thermo-gravimetry (TGA), Fourier Transformed Infrared Spectroscopy (FTIR), X-ray diffraction(XRD), and scanning electron microscopy (SEM) provided information on their composition and physical properties. In addition, cylindrical samples of 2 cm diameter were mold pressed and fired at temperatures ranging from 500 to 1000 ºC. We evaluated their technological properties as diametrical shrinkage, water absorption, and diametrical compression. SEM, Mercury intrusion porosimetry(MIP), and XRD provided results of their microstructure. Results indicated that the investigated wastes are promising materials for use in many applications such as vitroceramic, foam, tiles, countertops, and flux material for silicate ceramics. |
