An alternative method for recycling municipal incinerator grate ash is proposed. The glassy powder is sintered to obtain glass-ceramic materials. The results obtained from mineralogical, physical and microstructural analyses show that it is possible to obtain dense finished products consisting of common silicate crystalline phases (wollastonite, diopside) by firing treatments with shorter time and lower temperature with respect to bulk devitrification. 20 refs.
