Properties and Structure of BaO-ZnO-B2O3 Glasses

摘要：

　　The effect of coordination number on glass properties was investigated by measuring the glass forming region,glass transition temperature,dilatometric softening temperature,density and chemical durability of the glasses.The coordination number of B and Zn in the system 20BaO-xZnO-(80-x) B2O3 glasses (x=0~40mol%) was measured by IR,respectively.No change in the coordination number (CN) of B was revealed,and the coordination of Zn was 4 at ZnO 10mol%,which increased the properties of glasses.On the other hand,the coordination number (CN) of B and Zn changed from CN4 to CN3,CN4 to CN6 over ZnO 20 and 10mol% respectively,which decreased the properties of glasses.
