Abstract

The properties of glass-ceramics produced from Cayirhan Thermal Power Plant fly ash by sintering was investigated by means of Differential Thermal Analysis(DTA), X-ray Diffraction(XRD) and SEM techniques. The mechanical, physical and chemical properties of the samples were also determined. The crystallites occurred in the microstructure of the samples were observed from the SEM micrographs of the samples. XRD patterns of the samples clearly showed that the main crystalline phase was diopside[Ca(Mg,Al)(Si,Al)(2)O-6]. It was also found that the mechanical and physical properties of the sintered glass-ceramic samples depended on the amount of the crystalline phase.
