Effect of Nd₂O₃ Addition on Crystallization Behavior of Li₂O–Al₂O₃–SiO₂ Glass-Ceramics

Abstract:

Li₂O-Al₂O₃-SiO₂ glass-ceramics doped with Nd₂O₃ were prepared by the melting method. The effects of Nd₂O₃ on the crystallization behavior of Li₂O-Al₂O₃-SiO₂ glass-ceramics were studied by DTA, XRD and SEM. With the increase of Nd₂O₃ content, the glass crystallization temperature arised. The SEM result indicates that the main crystal phase of Li₂O-Al₂O₃-SiO₂ glass-ceramics doped with Nd₂O₃ is β-quartz solid solution, for without doping Nd₂O₃ it is β-spodumene solid solution. These results shows that the crystallization temperature increases significantly by doping Nd₂O₃, and phase transition from β-quartz to β-spodumene is suppressed. The grain size increases with the increase of Nd₂O₃ content.
