Abstract
Glass and glass ceramics were obtained using steelwork slag as a raw material. Glass was melted at 1500°C and heat treatments were performed at 720°C for nucleation and at 883°C for crystallization. Differential thermal analysis (DTA), X-ray diffraction (XRD) and scanning electron microscopy (SEM), with energy dispersive X-ray spectrometer (EDX) were used to investigate glass and glass ceramics. The crystalline phases developed were diopside and augite. The final microstructure was made up of crystals uniformly distributed, with a size of 1 to 3.5 μm.
