Abstract
The effect of BaO addition on the crystallization of Li2O-Al2O3-ZnO-SiO2-TiO2- ZrO2 (LAZSTZ) glass was investigated and discussed. The crystallization temperature of BaO-added LAZSTZ precursor glass (LBAZSTZ) was decreased due to the increase in the number of broken ionic bonds, while the transparency of the glass-ceramic was maintained. The lowered activation energy for crystallization in LBAZSTZ glass strongly supports the increase in the number broken bonds. During heating LBAZSTZ glass, phase separation did not occur most probably due to the competition between metal cations having a certain degree of ionic field strength. The formation of β-spodumene as a major phase in LBAZSTZ glass-ceramic was identified using x-ray diffraction.
