| 摘 要： | 采用高温熔融法制备了不同配比的硼锂二元体系玻璃,并利用UVPC、NMR和DSC等手段研究了不同锂含量对玻璃透过率、结构和热稳定性的影响。结果表明:在硼酸盐玻璃中引入少量Li2O,[BO3]三面体会向[BO4]四面体转变,使玻璃的网络结构有所加强,热稳定性提高,且玻璃中非桥氧数量降低,紫外透过率升高;当加入过量Li2O时,产生断网结构,玻璃稳定性逐渐下降,非桥氧数量增加,导致紫外透过性能降低。

| Abstract: | The dualistic system of boron-lithium glass with different weight ratios was prepared by high-temperature melting.The effect of transmission,structure and thermal stability of the glass system with adding different li-thium content was investigated by means of UVPC,NMR and DSC.The results show that[BO_3]trihedron transforms into[BO_4]tetrahedron when a small amount of Li_2O is introduced into borate glass.So the glass network structure strengthen and thermal stability of the glass enhances.Also the ultravio... |
