Ternary oxide glass system of chemical composition of 80B(2)O(3)-(20-x)Na2O-xCdO (where x = 0, 2, 4, 6, 8, 10, 12, 14 mol%) have been prepared by conventional melting and quenching method. The micro structural and morphological investigation of synthesized glass samples were carried out by using XRD, FE-SEM. The supporting physical and composition dependent properties such as experimental and theoretical density, molar volume, oxygen packing density, ionic concentration, interionic distance and polaron radius were determined. Density of glass samples increases, while molar volume decreases with the increasing cadmium oxide concentration from 0 to 14 mol%. X-ray diffraction profiles and FE-SEM images confirmed amorphous nature of investigated glass samples. Elemental analysis and information about the chemical composition of glass matrices have been ascertained by using EDS spectra. The interpretation of functional groups [BO3] and [BO4] units present in the oxide glass was simulated by using deconvoluted Raman spectra and FTIR spectroscopy. B-O stretching, metal cation active vibrational modes and bending vibrations of B-O-B linkage in borate glass network are cross verified by using FTIR and Raman spectroscopy.
