Abstract

In order to revalorize industrial residues such as glass cullet waste, chamotte from defective tiles or fly ashes from a coal thermal plant, some compositions precursor of glass-ceramic materials have been formulated, using the diagrams used for the design of ceramic materials synthesized by petrurgic method (Gingsberg, Raschin-Tschetverikov and Lebedeva diagrams). The typical instrumental techniques (XRD, XRF, DTA/TG, dilatometer, particle size distribution by laser diffraction and heating microscope) have been used in order to characterize waste and compositions. Then, the TTT diagram (Time-Temperature-Transformation diagram) of each composition have been studied to find the optimum conditions to get the glass-ceramic glaze in the firing cycle of the porcelain stoneware tiles. Finally, the mechanic, chemical and magnetic properties have been studied in each case.
