Abstract

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.
