Bi2O3 Reinforced B2O3–SiO2–MgO Glass System: a Characterization Study Through Physical, Mechanical and Gamma Shields Characteristics

Abstract

The glass system with the compositions (15SiO₂-75B₂O₃- (10-x)MgO-xBi₂O₃, \(x\) = (\(0\le\) x \(\ge 10\)) in mol% has been formulated with the conventional melt quenching procedure. The amorphous character was verified with XRD. As an increase of Bi₂O₃ the (\(\rho\)) increased from 2.88 to 4.97 g/cm³ and (\({V}_{m}\)) declined from 22.66 to 21.69 cm³/ mol. The ultrasonic velocities were measured to evaluate elastic moduli. Using the theoretical Makishima-Mackenzie model to calculate elastic moduli provides a valuable tool for confirming the experimental results. Using the Phy-X tool, the radiation shielding properties were theoretically estimated. Evaluations have been done on linear and mass attenuation coefficients (MAC and LAC), the effective atomic number (Zeff), and electronic density (Neff). The observation was that shielding parameters are influenced by the concentration of Bi₂O₃ and photon energy. The observation was that MgBi-10 exhibited the highest density, highest elastic moduli, and highest radiation shielding factors such as (MAC), (LAC), (Zeff), and (Neff) among the glass samples. The observation was that the glass sample with 10 mol% Bi₂O₃ doping (MgBi-10) exhibited the best overall properties for both mechanical and radiation shielding applications.
