Grate fly ash and fluidized bed fly ash mixed with glass cullet additive respectively were melted in the electronic arc-furnace.The product,arc-melting slag,was further treated by crushing,pressing and heat treatment in order to make the glass-ceramics.The crystallization behaviors of the produced glass-ceramics were examined by differential thermal analysis (DTA),X-ray diffractometry (XRD) and scanning electron microscopy (SEM).Results show that main crystalline phase of the glass-ceramics from grate fly ash is wollastonite (CaSiO3) with small amount of diopside (Ca(Mg,Al)(Si,Al)2O6),and that from fluidized bed fly ash is diopside (Ca(Mg,Al)(Si,Al)2O6).It is found that the glass-ceramics sintered at 850 ℃ and 1000 ℃ from grate fly ash and fluidized bed fly ash respectively have the optimal physical,mechanical and chemical characteristics.Glass-ceramics samples,produced from incinerator fly ash with desirable properties and the low leaching concentration of heavy metals,can be the substitute of nature materials such as marble,granite and porcelain tiles.
