In Korean steel making industry is generating 25 billion tons of slag as industrial by-products per year. Uses of these slags to manufacture high functional abrasive material are of greater feasible option for sustainable development of industry as well as effectively solve the pollution issue associated with these waste. Recycling methods of slag have been actively studied for decades, but most of the slag recycling methods studied are related to low cost building materials. Recently, several combinations of by-products have been used in glass-ceramic manufacturing, mostly the abrasive materials are basalt based glass-ceramic. Using these industrial by-products instead of natural basalt ores, high functional product can be manufactured. This piece of investigation focused on the feasibility study for producing the basalt based glass-ceramic from recycled industrial by-products only, without any natural materials as raw materials. By controlling various process parameters like, mixture ratios of materials, heat treatment for casting, and soaking basalt based glass-ceramic were prepared. The prepared materials were characterized by X-ray diffraction (XRD), X-ray fluorescence (XRF), scanning electron microscope (SEM), thermo-gravimetry and differential thermal analysis (TG-DTA). Excellent material properties were observed.
