Abstract

Ceramic glazing sludge deriving from the purification process of waste-water obtained by the glazing tile phase was mixed in equal proportion with glass cullet in order to obtain a high sintered product suitable to be used as floor/wall covering tiles. The characterization of fired samples includes the evaluation of both sintering parameters: water absorption, linear shrinkage and apparent density according to the ISO rules and sintering temperatures estimated by optical heating microscope. Satisfactory results were achieved from technological tests and SEM analysis showed a dense microstructure with crystalline phases similar to commercial glass-ceramic, identified by X ray diffraction. Besides, the obtainment of these products was achieved with energy saving due to the lower firing temperatures (about 1000°C) with respect to commercial products for floor/wall covering (about 1200°C).
