Sanad, I. Kashif, A. El-Sharkawy, A. El-Saghier, H. Farouk] A barium borate glass system was prepared containing different amounts of iron. The prepared glasses were heat treated at 550° C for 2, 6, 12, 18 and 24 h. Also the glasses were irradiated usingψ-ray at a dose of 4.805 × 104rad h−1 for 12, 18 and 24 h. The infrared spectra were recorded for the untreated and heat treated samples. It was found that, when the Fe2O3 was introduced in the glass the triangle BO3 groups were transferred to BO4 groups. The formation of non-bridging oxygen with high concentration was also observed as a result of introducing Fe2O3 in the glass. The absorption bands of the IR spectra of the irradiated samples indicated no significant variations, and only a transfer of some BO4 groups to BO3 groups could be observed.
