We prepared porous ceramics by mixing the fly ash from a thermal power plant with waste glass to resolve the environmental waste recycling problems. Applying the mechanical milling method and annealing procedure, powder mixtures consisting of waste glass powder (70 wt%) and fly ash (30 wt%) were used at various heat treatment temperatures of 600, 650, 675 and 700 οC to obtain porous ceramics with a variety of structural and mechanical properties. The pore structure was substantially affected by the starting raw materials and annealing temperatures. The pore formation mechanism is discussed in relation to these effects. In the present study, the crystallinity and morphological properties were observed by X-ray diffraction (XRD) and field emission-scanning electron microscopy (FE-SEM). Various properties, such as bending strength and Brunauer- Emmett-Teller (BET) absorption were also examined.
