Barium aluminoborate glass of composition: xBaO-yAl2O3- (100-x-y) B2O3 -2yNaCl, with y = 3 and x = 3, 8, 13, 18 and 23 mol % were prepared, its structure and properties were also investigated. The structure was examined using Fourier Transform Infrared (FTIR) spectroscopy. The D C electrical conductivity and glass density were also measured. The analysis of the FTIR spectra revealed that there are seven absorption peaks with three quite active ones lying in the following regions: 1200 – 1600 cm-1 , 800 – 1200 cm-1 and 600- 800 cm-1 which are consistent with previous data reported by many authors. These peaks represent the absorption of the structure units that consists the glass matrix. The change in the position and relative area of these peaks demonstrates the structural modification accompanied with the change of the glass composition.
