Preparation and Characterization of Glass-Ceramic Synthesized from Soda Lime Glass and Wastewater Sludge

This paper reports an alternative method for making glass-ceramic from disposal waste water sludge and soda lime silica (sls) glass. the glass ceramic samples were prepared from a mixture of wastewater sludge and sls glasses, melted at 1375°c for 3 hours and quenched by pouring into water to obtain a coarse frit. the frit glass was then crushed and sieved to 106μm before it was pressed to a pellet. the sintering process was performed at various temperatures between 700-1000°c for 2 hours and morphologically characterized with xrd, sem, and edx. overall results showed the crystalline phase of diopside sodian-critobalite glass-ceramic is depending on thermal treatment process and making them attractive to industrial uses such as in construction, tiling, and glass-ceramic applications.
