High mechanical resistance glass-ceramic tiles prepared from solid wastes

Treball Final de Grau en Química. Codi: QU0943. Curs acadèmic: 2020/2021 The development of new glass-ceramic tiles by sinter-crystallization method have been investigated using solid wastes (ceramic polishing, soda-lime-silicate glass, eggshell, mussel shell and industrial sludge’s). Chemical compositions of wastes and glass-ceramic samples were studied by X-ray fluorescence (XRF) and thermal analysis (TG/DSC). Structural characterization by X-ray diffraction (XRD) measurement revealed the crystalline phases depending on process parameters. The morphology of glass ceramic samples was characterized by scanning electron microscopy (SEM/EDX). The apparent density values were between 1,47 and 1,79 g/cm3 . Flexural strength values range between 52,09 and 97,76 N/mm2 . The experimental compositions allowed reutilizing residues to produce high mechanical resistance glass ceramic tiles with suitable properties and environmental profits.
