Abstract

Borate mineral wastes and phosphate ash resulting from the incineration of meat and bone meal represent two particularly abundant inorganic wastes. This paper is dedicated to the combination of such wastes, together with kaolin clay, focused on the development of highly porous ceramic bodies. Borate waste has a multiple effect, providing liquid phase at the sintering temperature (1050°C), gas release (from the decomposition of its calcite fraction) and a CaO source, which reacts with residues from clay and promotes the formation of anorthite crystals as a newly formed phase. Control of the heating rate, i.e. adoption of fast heating (20°C min -1) and, above all, introduction of recycled soda-lime-silica glass as secondary additive, allowed obtaining lightweight microporous bodies (density below 0·45 g cm -3) with uniform pore structure that could be useful for thermal and acoustic insulations. © 2012 Institute of Materials, Minerals and Mining.
