Abstract:

Microstructural evolution on heating kaolinite clay, quartz, nepheline syenite, and soda–lime–silica (SLS) glass to various temperatures to 1300°C was investigated in quenched and slowly cooled samples by XRD, thermal analysis and SEM, and by in situ XRD. In the individual components, the expected behavior was observed and in SLS glass, devitrification led to crystallization of cristobalite, quartz, devitrite, and wollastonite, which dissolved at 900°–1000°C. Significant effects of each component on microstructural evolution in the others were often observed in binary mixtures. For example, in SLS glass and quartz mixtures, devitrification of SLS glass to form cristobalite was delayed and two forms of cristobalite with different morphologies were identified. Albite and plagioclase crystallized on heating kaolin clay and SLS glass mixtures, decreasing the alumina content available for mullite formation. Melting of nepheline syenite promoted reaction with the clay, including accelerated phase dissolution. SLS glass accelerated dissolution of nepheline syenite and prevented leucite formation.
