Influence of fluorine content on the crystallization and microstructure of barium fluorphlogopite glass-ceramics

Abstract
Abstract The effect of varying the fluorine content on the nucleation and crystallization behavior of barium containing glasses based on the system BaO·4MgO·Al2O3·6SiO2·2MgF2 was investigated by differential thermal analysis (DTA), X-ray diffraction (XRD) and scanning electron microscopy (SEM). Both the crystallization peak temperature (Tp) and activation energies (E) decreased, the Avrami exponent (n) and pre-exponential factor (ν) increased. The results suggest that fluorine increases the rate of diffusion in the glass and promotes initial crystallization in barium fluorphlogopite glasses.
