چکیده

In this study, production possibility of glass and glass-ceramic produced from granite was investigated. The composition of granite based glass bath mixture was 50 wt% granite, 25 wt% dolomite and 25 wt% sodium carbonate. Composition that was grounded and mixed in a ball mill for 2 h was melted at 1500 ◦C for 1 h. Glass samples were heat treated for crystallization to produce glass-ceramic materials at 800 ◦C, 900 ◦C and 1000 ◦C for 2 h to promote internal crystallization. Phase identi cations of glass and glass-ceramic materials were investigated by X-ray di raction analysis. Moreover, hardness and fracture toughness measurement of glass and glass-ceramic materials were applied. Granite based materials after that melting and casting process was found amorphous state by characterization with X-ray di raction analysis. After the heat treatment processes, crystal phases settled out in glass matrix were also determined in granite based materials. Moreover, values of hardness and fracture toughness increasing were detected by heat treatment schedule.

Effect of iron oxide content on the crystallisation of a diopside glass–ceramic glaze

The effect of iron oxide content on the crystallisation of a diopside glass–ceramic glaze was investigated using a glass–ceramic frit in the K2O–ZnO–MgO–CaO–Al2O3–SiO2 system and a granite waste glass. Measurements by X-ray diffraction (XRD) combined with scanning electron microscopy (SEM) and EDX microanalysis showed that the distribution of Fe ions among different crystalline phases such as f...
