通过红外光谱,对不同组成的ZnO-B_2O_3-SiO_2体系玻璃的网络结构进行了研究,分析了ZnO-B_2O_3-SiO_2玻璃体系的组成改变所引发的基团结构变化.结果发现:ZnO大于30%时,Zn进入B-O-Si网络形成Zn-O-B或Zn-O-Si键;ZnO含量大于40%时,形成[ZnO4]四面体;同时,ZnO含量的增加还会促使[BO3]向[BO4]的转变,以致形成高硼基团;SiO_2/B_2O_3比增加同样会导致Zn-O-B或Zn-O-Si键以及[ZnO4]单元的数量增加,同时也会使得[BO3]向[BO4]的转变,并趋于形成高硼基团.

Glass structures with different components of ZnO-B_2O_3-SiO_2 were investigated by using the Fourier transform infrared spectra. The relationship between the glass structure and components was also analyzed. The results show that when concentration of ZnO is greater than 30%, Zn2+ entered into B-O-Si net, Zn-O-B bond and Zn-O-Si bond are formed and when concentration is greater than 40%, [ZnO_4] units are formed. Otherwise, [BO_3] units are changed into [BO_4] units with the increasing of ZnO content.The growing of SiO_2/ B_2O_3 ratio also introduces the increment of Zn-O-B bonds, Zn-O-Si bonds and [ZnO_4] unitses.At the minetime, [BO_3] unitses also turn to[ BO_4]unitses, and they tend to form boron oxygen polymer groups.
