A STUDY OF RAMAN SPECTRA OF GLASSES IN THE Li2O-B2O3-SiO2 SYSTEM

Abstract
In the Li2O-B2O3-SiO2 glasses with Li2O≥30 mol%, substitution of Li2O for B2O3 or SiO2 leads to increase the amount of borate and silicate groups with non-bridging oxygen in glass network; while substitution of B2O3 for SiO2 leads to increase the amount of borate groups with or without non-bridging oxygen and silicate groups with non-bridging oxygen.
