| Abstract | The crystallization tendency resulting from liquid-liquid separation in CaO-MgO-Al2O3-SiO2-Fe2O3 glass-ceramic has attracted much attention. However, the structural origin of this effect is still poorly understood. In this paper, spectroscopies were used to analyze the silicon-oxygen network structure of the basic glass with different iron oxide contents. With a focus on the microenvironment of iron atoms, the isolated iron was converted to clusters as the Fe2O3 content increased. Based on the above findings, two iron-containing cluster structures that affect the glass stability and crystallization potential are proposed. Liquid-liquid phase separation was clearly observed by transmission electron microscopy. Thermal analysis proved that the increase in the formation of clusters weakened the glass stability. This study not only provided data for understanding the exceptional microstructure of CaO-MgO-Al2O3-SiO2-Fe2O3 glass but also yielded profound insights into the metastability of glass-ceramics. |
