Optical and Physical Properties of Magnesium modified Borate Glass System

The glass system with composition 55B(2)O(3)center dot 10K(2)O center dot(35-x)CaO.xMgO (x=0,5,10,15) has been prepared using normal melt quench process. XRD measurement was done to verify the non-crystalline nature of the glass system. The glass transition temperature was calculated using DSC and was found to increase initially at low content of MgO and decreased at high content of MgO. Various physical properties density, molar volume are also calculated. The optical band gap is measured using UV-VIS spectroscopy.
