Production of glass-ceramic from incinerator fly ash

Abstract Vitrification is one of the technological options for treating toxic waste. This paper reports the results of the feasibility study of utilizing fly ash from municipal waste incinerators by powder sintering technology. This process was used to transform vitrified incinerated fly ash into a CaO–Al2O3–SiO2 system of glass ceramic products. The major phase exhibited is gehlenite (Ca2Al2SiO7), which belongs to the melilite group. The glass-ceramics exhibited attractive physical and mechanical properties. The products can be fabricated at 900 °C/2 h for construction purposes and have large application potential.
