摘要：
The crystallization and microstructure of Li2O-Al2O3-SiO2 (LAS) glass ceramic with complex nucleating agents (TiO2 + ZrO2 + P2O5 +/or F-) are investigated by differential thermal analysis (DTA), X-ray diffraction (XRD) and scanning electron microscopy (SEM), and the effects Of P2O5 and F- on the crystallization of LAS glass are also analyzed. The introduction of both P2O5 and F- promotes the crystallization of LAS glass by decreasing the crystallization temperature and adjusting the crystallization kinetic parameters, allows a direct formation of spodumene without the transformation of LiAl(SiO3)(2) into beta-spodumene and as a result, increases the crystal size and crystallinity of LAS glass ceramic.
