Characterisation of glass ceramics made from incinerator fly ash

Abstract The feasibility of recycling the incinerator fly ash from domestic waste incineration by developing a process to produce glass and glass-ceramic materials has been investigated. Quenched glass was obtained by high temperature molten technology. A one-step sintering and heat treatment at various temperatures (i.e. 850, 900, 950, 1000 and 1050 °C) was used to obtain glass-ceramics after pressing the quenched glass powder. A porous glass-ceramic material was formed with gehlenite (Ca 2 Al 2 SiO 7 ) as the main crystal phase.
