【摘要】 在Li₂O≥30mol％的Li₂O-B₂O₃-SiO₂系统玻璃中,以Li₂O代B₂O₃或SiO₂都导致玻璃网络中带非桥氧的硼酸盐和硅酸盐基团的量的增加;以B₂O₃代SiO₂则使玻璃网络中带和不带非桥氧的硼酸盐基团以及带非桥氧的硅酸盐基团的量都增加。更多还原

【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.更多还原
