Abstract
B2O3-PbO-MgO glasses with different concentration of MgO (3-12 mol. % in the steps of 3) were prepared by melt quench technique. Structural characterizations of these glasses were studied through FT-IR and DTA measurements. The amorphous nature of the glasses was checked by X-ray diffractometry. The transformation of BO3 trigonals to BO4 tetrahedral units has evidenced from the FT-IR spectra of the prepared glass samples and the BO4 structural units increases with an increasing concentration of MgO content. The transition temperature, melting temperature and crystallization temperature have been identified using DTA measurements. The transition temperature increases with an increase of MgO content. The structural properties of these glasses were discussed in terms of the relative proportion of lead and magnesium oxides.
