用双辊急冷法把Li_2O-B_2O_3-WO_3系统的玻璃形成范围扩大了近二倍。IR 光谱和Raman光谱研究表明:少量WO_3取代B_2O_3时,W~(6+)离子以四配位存在并进入网络;引入多量WO_3时,[WO_4]增多并出现[WO_6],WO_3取代B_2O_3使玻璃稳定性下降,使导电率和介电常数增大。观察了30Li_2O·xWO_3·(70-x)B_2O_3玻璃在0.1N H_2SO_4非水性溶液中的电致色效应,发现着色速率与玻璃的电导率无关,而与WO_3含量成正比关系。
In the system Li_2O-B_2O_3-WO_3,the glass forming region was extended twotimes by use of twin-roller quenching technique.Infrared and Raman spectrum revealedthat W~(6+)ion is located in the tetrahed-rally coordinated oxygen ligands and participated innetw
