Abstract

Sintered glass-ceramics have been produced using municipal incinerator solid residues and glass culler or an inert waste, from feldspars processing, as sintering aids. The capability of three different mixtures, either previously vitrified or not, to be sintered was investigated by means of linear shrinkage, water absorption and bulk density measurements, and by X-ray diffraction analysis and scanning electron microscopy observations. Particular attention has been addressed to the study of particle size effect on the sintering process. The conclusions that can be drawn from the experimental study are that the preliminary vitrification step is essential in order to obtain a dense sintered glass-ceramic product in the 850-1050°C temperature range developing silicate crystalline phases. The optimal powder particle size that confers a good densification degree was found to be < 45 μm.
