Borate bioactive glasses (BBGs) have been the subject of substantial research for biomedical uses since the early 2000s. BBGs with the composition of (X) MnO2 ((45-x) B2O3, 24.5CaO, 24.5Na2O, 6P2O5) where x = (0, 0.1, 0.2, 0.3, 0.4, 0.6, and 0.8) were prepared using the conventional melt-quenching technique through replacing the MnO2 on the expense of B2O3 content. Synthesized BBGs were investigated via X-ray diffraction (XRD), Fourier transforms infrared (FTIR), and Ultraviolet (UV-Vis) spectroscopy. Additionally, several estimated and calculated physical parameters including density, molar volume, molecular mobility, average boron-boron, boron atoms’ molar volume, ion concentration, polaron radius, and field strength were correlated to the structural variations.
