Abstract

The devitrification routes of vitrified materials containing chromium-loaded ash were studied in this work. Chromium-loaded ash originates from the incineration of tannery sludge. Vitrification was applied using SiO2, Na2O and CaO. Three different batch compositions were studied with the relative proportions of SiO2 and Na2O kept constant, and varying proportions of chromium-loaded ash and CaO. All vitrified products were thermally treated in order to produce glass–ceramic materials, i.e. to induce devitrification. Thermal treatment temperatures were selected by application of differential thermal analysis. All products were characterized with X-ray diffraction, scanning electron microscopy and energy dispersive spectrometry. The resulting glass–ceramic products possessed different microstructures, i.e. composition, morphology and spatial distribution of separated ceramic phases, depending on the chromium-loaded ash content and thermal treatment temperature. The results show that a combination of differential thermal analysis with morphological, structural and elemental characterization methods renders microstructural tailoring and control of physical properties feasible.
