Abstract

Crystallization and sintering behaviors of four β-spodumene (Li₂O-Al₂O₃-4SiO₂) glasses having different compositions were investigated and compared by differential thermal analysis (DTA), X-ray diffraction (XRD), and scanning electron microscopy (SEM). The Li₂O-Al₂O₃-4SiO₂ glass containing both B₂O₃ and TiO₂ showed the lowest activation energy value for crystallization (220 ± 8 kJ/mol), whereas the stoichiometric Li₂O-Al₂O₃-4SiO₂ glass showed the highest value (322 ± 4 kJ/mol). The crystallization peak temperature (T_p) decreased from 918 to 819°C by the addition of both B₂O₃ and TiO₂ to the stoichiometric Li₂O-Al₂O₃-4SiO₂ glass. The Li₂O-Al₂O₃-4SiO₂ glass containing both B₂O₃ and TiO₂ showed approximately the same degree of sintering as the Li₂O-Al₂O₃-4SiO₂ glass containing only B₂O₃.
