Influence of Industrial Solid Waste on the Chemical and Mechanical Properties of Traditional Glaze-Ceramics

Abstract

New glaze compositions were synthesized from combinations of ceramic glaze and cement kiln dust. The products show very good chemical resistance to acid and alkaline corrosion, with no visual changes on the surfaces of the samples. This resistance can be attributed to the very well balanced composition of wastes and commercial ceramic glaze materials. Corrosion data reveal the results of mass loss either at 25 ℃ or 100 ℃. The mass loss is very low, showing that it is possible to develop glazes with excellent chemical resistance to strong acid and alkaline solutions corrosion starting from different concentrations of cement kiln dust associated with commercial ceramic glaze materials. The IR spectra of the prepared samples show characteristic bands related to the vibrations of triangular and tetrahedral borate and tetrahedral silicate groups together with metal-oxide groups. The surface hardness data of the glazes determined by Mohs are found to be 5–6 at early immersion times up to ∼9 days, but there is obvious deterioration beyond 9 days. The results point out that it possible to deepen the understanding of the mechanisms of elements released through the chemical attack and their implications on microstructural and mechanical degradation of the working surface of glazed ceramic tiles.
