Abstract
(30-x) BaO-xAl2O3-69.5B2O3-0.5MnO2 (0 ≤ x ≤ 15 mol%) (BABM) glasses have been prepared using melt quench method. In the present work, the main focus on the role of Al2O3 in the glass composition. Differential scanning calorimeter (DSC) studies show that a glass transition temperature (Tg) decreases with an increase of Al2O3 content which was explained on the basis of NBO’s. The FTIR spectra exhibit to know BO3 and BO4 structural units, band assignments confirms Ba2+, Mn-O and bending vibration of Al-O in [AlO4]. The Raman band at~786 cm-1 has clearly shown the presence of aluminium bond. It has been found that an increasing the Al2O3 content increases the bond length of the Al-O bond in AlO4 which leads to an increase in molar volume and decrease density.
