Using a melt quenching procedure, bario-borate sodium glasses with varying concentrations of manganese ions (60B2O3-20NaF-(20-x)BaO-XMnO, where X = 0 (Mn-0.0) − 0.5 (Mn-0.5%mol%) were created. The impact of manganese ions on the structural, physical, radiation shielding, and dielectric properties of the Mn-X samples was examined. X-ray diffraction measurements confirmed that Mn-X samples were in an amorphous state. The measured density (ρ) slightly decreased upon the addition of MnO. In the low-frequency interval, the dielectric constant (ε′) declined significantly as the frequency increased. As the MnO content rose to 0.2 mol%, the ε′ value was clearly decreased, but, at higher concentrations, it increased. The glass specimen that had been modified by 0.2 MnO had the lowest dielectric constant, making it a suitable option for packing materials. The tan δ of the examined glasses displayed relaxation peaks. The ability of the prepared glasses as γ-ray shields was investigated using Phy-X/PSD software. The linear attenuation coefficient (LAC) of the proposed Mn-X glasses followed the order: Mn-0.0LAC > Mn-0.1LAC > Mn-0.2LAC > Mn-0.3LAC > Mn-0.4LAC > Mn-0.5LAC. The observed LAC trend can be explained by the glasses being less dense as the MnO component rises. The half-value layer (HVL) followed the trend: Mn-0.0HVL < Mn-0.1HVL < Mn-0.2HVL < Mn-0.3HVL < Mn-0.4HVL < Mn-0.5HVL. The tenth-value layer (TVL) has the same trend as the HVL. The effective atomic number (Zeff) and effective electron density (Neff) for all the proposed Mn-X glasses have the same trend. The Mn-0.0 glasses are located at the mid-point or at a suitable point among the commercial concrete materials as γ-ray shields. [ABSTRACT FROM AUTHOR] |
