Effects of TiO2 and P2O5 on solarization and crystallization of photosensitive lithium silicate glass
Source abstract
Abstract
Abstract In this study, the parent photosensitive glass and glass-ceramic in the system of lithium silicate containing AgCl under radiation of ultraviolet (UV) light were successfully prepared by melting process. Besides, the effects of adding TiO 2 and P 2 O 5 as nucleating agents on the solarization and crystallization of lithium silicate photosensitive glass were studied. The characteristics of the samples were identified by ultraviolet-visible absorption spectroscopy (UV-Visible), simultaneous thermal analysis (STA-TG/DTA), X-ray powder diffraction (XRD), and scanning electron microscopy (SEM). The results showed that adding P 2 O 5 in the amount of 2 wt.% to this system could be an acceptable nucleating agent, while adding 4 wt.% TiO 2 to it resulted in shielding behavior against the UV light. Therefore, this amount of TiO 2 is not successful in both solarization improvement and nucleation process. In addition, lithium disilicate crystalline phase formed only in the samples containing P 2 O 5 .
