Preparation of Decorative Building Glass-Ceramics by Using Cracked-Glass Panel as Precursor

Article Preview

Depending on surface and crack crystallization mechanism, a new type of glass-ceramics as a decorative building material has been obtained by using cracked-glass panel as precursor to replace glass grains used in conventional sintering process. In the comparative and parallel experiment, cracked-glass panels and glass grains were made from the same glass melt belonging to CaO-Al2O3-SiO2 family, and were heat-treated parallelly and transformed into two types of glass-ceramics tagged as CG-GCs and GG-GCs respectively. XRD patterns and SEM micrographs of CG-GCs demonstrate that cracked-glass can deposit β-wollastonite. Properties tests show that the compactness of CG-GCs is higher than that of GG-GCs, signifying that, in comparison to glass grains in conventional sintering process, using cracked-glass panel as precursor in this study can reduce the porosity of end products. In addition, it is of great interest that the polished surface of CG-GCs can exhibit excellent texture much different from granular one of conventional GG-GCs.
