Investigation of Nucleation and Crystallization Behavior of Li₂O-MgO-Al₂O₃-SiO₂-MgF₂Glass-Ceramics System

Abstract:

The glass-ceramics were produced via heat treatment from bulk base glass at the appropriate treatment temperatures provided by the differential thermal analysis (DTA) measurement. The effect of nucleation on crystallization kinetics has been explored. It is found that nucleation indeed decreased the activation energy of crystallization. X-ray diffraction (XRD) analysis demonstrated that the main crystalline phase was magnesium alumino-silicate (MgAl₂Si₃O₁₀), Scanning electron microscopy (SEM) morphology showed that the crystals were needle-like in all the samples.
