Recycling of Glass Waste in Ceramics-Part II: Microstructure of Ceramic Products using XRD, DTA and SEM Techniques

The current study is to follow the previous published paper about the physical, mechanical and thermal characteristics of traditional ceramic composites incorporating different ratios of glass waste. The phase composition and/or microstructure of the optimum ceramic batch (G5) compared with those of the blank (G0) was investigated by X-ray Diffraction Patterns (XRD), Differential Thermal Analysis (DTA) and Scanning Electron Microscopy (SEM). The XRD analysis proved that the resulting ceramic product exhibited higher strength than that of the blank due to the formation of new ceramic phases which were responsible for the higher values of densification parameters as well as mechanical strength. The DTA thermo grams illustrated the dissociation and conversion of the various phases. The SEM micrographs showed that the well crystallized and well developed crystals of G5 offered the excellent external apprearrans and/or microstructure of the samples incorporated glass waste.
