摘要

The sinter-crystallization ability of two glasses obtained by post-treated bottom ash of municipal solid waste incinerator (MSWI) at two particle size (coarse and fine) was investigated. The phase formation was estimated by DTA and XRD, while the sintering process was evaluated by optical dilatometry, linear shrinkage and water absorption. The porosity variations were estimated by density measurements. The microstructure and morphology of the glass-ceramics were observed by scanning electron microscopy. This integrated experimental approach together with theoretical study (by the methods of Ginsberg, Raschin-Tschetveritkov and Lebedeva) permitted to establish a better sinter-crystallization ability for the glass obtained from coarse MSWI ash fraction.
