Characterization of ceramic tiles containing LCD waste glass

Abstract In the present work, the application of LCD waste glass as a flux material substituting for the traditional feldspar in ceramic tiles was studied. The viscosity of LCD glass at the sintering temperature of the ceramic tile was found to be optimal for the dense solid that is obtained from the sintering of the glass powder. The sintered body containing LCD waste glass showed a dense microstructure due to the rich liquid. Even for full replacement of feldspar, neither pyroplastic deformation nor liquid exudation was observed. Overall, properties such as water absorption and the thermal expansion coefficient were positively affected by LCD waste glass substitution. Moreover, the mullite content in the sintered body was almost unchanged. These results were discussed in terms of the apparent viscosity and glass composition.
