中文摘要	A study has been carried out on the feasibility of using a high iron content fly ash, generated during steel making, as a raw material for glass ceramic production. The fly ash was mixed in different proportions with soda-lime glass cullet and sand. The devitrification of the parent glasses produced from the different mixtures was investigated using differential thermal analysis, X-ray diffraction and scanning electron microscopy. The mechanical properties of the glass-ceramics were assessed by hardness and indentation fracture toughness measurements. A glass ceramic with composition of 60 wt-% fly ash, 25 wt-% sand and 15 wt-% glass cullet and containing magnetite in a marked dendritic morphology exhibited the best combination of properties, namely, hardness 7(.)9 GPa and fracture toughness 3(.)75 MPam(0.5). These new hard glass-ceramics are proposed for wear resistant tiles and paving for heavy duty industrial floors. In powder form, the glass ceramics are candidate materials for blasting and abrasion applications.
