Barium alumino borate glasses are prepared for the composition (30-x) BaO-xAl2O3-69.8B2O3-0.2Cr2O3 (0 ≤ x≤ 15 mol %) to be specified as BABCrsynthesized by making the use of melt quenching process. These glasses are analyzed using different instrumental techniques. X-Ray Diffraction (XRD) is used to ascertain the glassy nature. Various physical properties are carried out to get the information regarding BO3, BO4 and NBO's. From the observation of Differential Scanning Calorimetry (DSC) spectra, Tg decreases in accordance with increasing the amount of Al2O3 content. In the present study, the addition of Al2O3 to the BaO-B2O3 glass is studied and its role in the glass is being observed by Fourier Transform Infrared Spectroscopy (FT-IR) vibrational spectra. From Raman studies of BABCr glasses,it is observed that thepresence of Al-O-Al linkages and AlO4 units in the region 500 to 780 cm-1. The large segment of B-O groups observed at higher wavelength of Raman spectra. The increment of Al2O3 content in the glass composition results the increment in Raman intensity.
