摘要

In this paper, the effect of boron-aluminum anomaly on the structure-performance of alkali-free glass substrates is investigated, aiming to provide key guidance for the optimization and transformation of display devices. Mainly using XPS, infrared, glass modeling and performance analysis, the survey results show: As the substitution of B2O3 for Al2O3 reaches 8wt%, the boron-aluminum anomaly appears (B-3 -> B-4 , Al-4 -> Al-6), causing extremum of performance to occur. The whole process also affects the Q(n) family, as the coordination number of B and Al points to 4, the Q(n) family is more inclined to Q(4), and vice versa. Moreover, the coordination status of B and Al does not completely follow the RO/Al2O3 ratio due to the secondary polarization of O2- caused by the high field strength of R2+. The glass obtained in this study basically meets or even far exceeds the requirements of substrate usage, which has certain referenced significance for the actual display industry.
