Significant influence of MoO3 content on synthesis, mechanical, and radiation shielding properties of B2O3-Pb3O4-Al2O3 glasses

The melt-quench method was used to create our amorphous with the chemical formula 55BO(2)-30Pb(3)oO(4)-(15 - x) Al2O3 - xMoO(3), :(0 <= x <= 5). The purpose of the article is to search and investigate the structural, mechanical characteristics, and radiation proficiency features of prepared glasses. The nature of these glasses has been tested using XRD analysis. Furthermore, the molar volume was obtained, and it decreased with the addition of MoO3 content while the density increased. The mechanical properties were enhanced of the current glass sample by adding MoO3 to modify the glass structure. The ultrasonic speeds (vv,LT) and L, G, Y and K of present glass were observed to improve. The radiation shielding performance of the produced glassy samples was assessed via Geant4 simulations and directly through the Phy-X/PSD software. Analysis of obtained results showed that the photon shielding proficiency of the present glassy specimens improved with the increase of MoO3 content. The calculated neutron removal cross section of the glasses grew from 0.07125 to 0.10822 cm(-1) as MoO3 content rise from 0 to 5 mol%. The gamma ray and fast neutron absorbing ability of the glass with the highest MoO3 content was superior among the presently investigated glasses and some conventional shields. (C) 2021 Elsevier B.V.
