Abstract
This study investigates the structural, mechanical, and radiation protection behavior of sodium phosphate glasses modified with 30 mol% Nb₂O₅ and varying MnO concentrations (0–7.5 mol%). Seven glass samples (S1–S7) were synthesized via the melt-quenching technique and characterized using FTIR, XRD, Vickers hardness testing, and MCNP simulations combined with XCOM theoretical calculations. FTIR analysis revealed that Nb₂O₅ primarily adopts octahedral coordination (NbO₆), acting as a network modifier, while MnO exhibits dual roles: Mn²⁺/Mn³⁺ ions modify the phosphate network at lower concentrations and participate in structural unit formation at higher concentrations. XRD confirmed the amorphous nature of all…
