Nano-phase separation and structural ordering in silica-rich mixed network former glasses
Abstract
We investigate the structure, phase separation, glass transition, and crystallization in a mixed network former glass series, i.e., B 2 O 3 -Al 2 O 3 -SiO 2 -P 2 O 5 glasses with varying SiO 2 /B 2 O 3 molar ratio. All the studied glasses exhibit two separate glassy phases: droplet phase (G 1 ) with the size of 50-100 nm and matrix phase (G 2 ), corresponding to a lower calorimetric glass transition temperature (T g1 ) and a higher one (T g2 ), respectively. Both T g values decrease linearly with the substitution of B 2 O 3 for SiO 2 , but the magnitude of the decrease is larger for T g1 . Based on nuclear magnetic resonance and Raman spectroscopy results, we infer that the G 1 phase is rich in boroxol rings, while the G 2 phase mainly involves the B-O-Si network. Both phases contain BPO 4 - and AlPO 4 -like units. Ordered domains occur in G 2 upon isothermal and dynamic heating, driven by the structural heterogeneity in the as-prepared glasses. The structural ordering lowers the activation energy of crystal growth, thus promoting partial crystallization of G 2 . These findings are useful for understanding glass formation and phase separation in mixed network former oxide systems, and for tailoring their properties.
