dc.description.abstractGlasses withcompositions 46.1B2O3-24.4Na2O-26.9CaO.2.6P2O5, xZnO/MgO-22.0B2O3-(24.4-x)Na2O-27CaO-2.5P2O5 (x = 2.5, 3 mol%) and 1.5ZnO-1.5MgO-22.0B2O3-21.5.Na2O-27CaO-2.5P2O5 were melted by melt quenching technique. The densities of the glasses were measured by the Archimedes principle, using an analytical scale. Glasses possess densities in the 2.538 to 2.623 g cm-1 range. The short-range order was also discussed from the molar volume Vm, cm3 mol-1, and oxygen packing density point of view. The molar volume of the glasses varies between 26.566 - 27.420 cm3 mol-1 and the oxygen packing density is between 73.669 to 76.262 mol cm-3. The Furie transform infrared spectroscopy and Raman spectroscopy were performed to study the main structural units constituting the structure of the samples. The main structural units were found to be BO3 and BO4 probably connected in pentaborate and triborate structural units. The influence of the ZnO and MgO on the structure and chemical bonding of the glasses was discussed.
