摘要

The effect of varying B_2O_3content on the crystallization and microstructure behavior of barium-containing glasses based on the system BaO·4MgO·Al_2O_3·6SiO_2·2MgF_2 was investigated by differential thermal analysis (DTA), X-ray diffraction, and scanning electron microscopy. Heat treatment of glass specimens in the form of fine powders in the range of 884℃-901℃ led to the formation of barium fluorophlogopite. DTA study revealed that the glass transition temperature (T_g) and crystallization peak temperature (T_p) decreased by increasing B_2O_3 content. It was also found that the higher the B_2O_3 content, the higher the aspect ratio of fluorophlogopite crystal.
