From the study, the optically transparent glass from BST system was successfully prepared by using melt-quench method. The composition of BST used in this study are ranging between 20-60 wt.% BST. It was found that the addition of BST enhanced conductivity, but in turn reduced the percentage of transmittance in the glasses. The dielectric constant (∈ r ) of the BST/Na 2 O-B 2 O 3 -SiO 2 glasses improved with increasing the content of BST, which in turn plays an important role in controlling the properties of the BST/Na 2 O-B 2 O 3 -SiO 2 glasses.
