Studying structural, mechanical, and radiation shielding properties for BaO–Li2B4O7–SiO2–MgO glasses

Year: 2025

Type: article

Abstract: : This article investigates the impact of the inclusion of BaO on the structural, mechanical, and γ-ray shielding of the glass composition 77Li 2 B 4 O 7 -11SiO 2 - (12-x)MgO-xBaO (0≤x≥12 mol%). FT-IR confirms the inclusion of BaO increases BO 4 and decreases BO 3 . The density increased from 2.89 for LBSMBa0 to 3.83 for LBSMBa12, while the molar volume decreased from 49.02 for LBSMBa0 to 40.53 for LBSMBa12. Both velocities were increased, (V L m/s) increased from 4634 for LBSMBa0, to 4890 for LBSMBa12, while (V T m/s) increased from 2165 for LBSMBa0 to 2318 for LBSMBa12. The elastic moduli values of LBSMBa glasses were increased. Phy-x code confirms the positive impacts of BaO on effects on the shielding efficiency. The MAC values of LBSMBa glasses have the trend: LBSMBa12> LBSMBa9 > LBSMBa3 > LBSMBa1.5 > LBSMBa0. Thus, the LBSMBa12 sample can be used in shielding applications more than the other samples.
