Mechanical and radiation shielding features of lithium titanophosphate glasses doped BaO

Glasses with the formulation 15TiO2-70P2O5 -(15 -x) Li2O-x BaO x = (0 < x < 10 mol. %) are fabricate by the melt quenching procedure. As BaO concentration increased, the observed density increased and the predicted molar volume decreases. To assess the elastic prop-erties of glasses, ultrasonic velocities were measured. Ultrasonic velocities (VL& VT) in-creases as the amount of BaO content increases. The higher connection strength of BaO proportional to Li2O as well as an increment in coordination number results in an incre-ment in elastic moduli. The Phy-X/PSD program was also used to describe the samples' gamma-ray shielding parameters, like the mass attenuation coefficient (MAC) (cm2/g). According to studies on radiation shielding in glasses, the BaO content is the only factor affecting the radiation shielding phenomenon. All the samples have (MAC) values of 7.868, 9.177, 10.432, 12.794, 13.907, and 0.021, 0.022, 0.022, 0.023, and 0.024 at lower and higher energies. One can deduce that BaO reinforcement has multiple functions, including increasing the density of comparable glass compositions and thus their mechanical and gamma-ray shielding properties. This study suggests, there is a strong correlation between the mechanical and radiation properties of the glasses.(c) 2023 The Author(s). Published by Elsevier B.V.

Automated summary

Glasses with different BaO content in the formulation 15TiO2-70P2O5-(15-x)Li2O-xBaO (0 < x < 10 mol. %) were fabricated using the melt quenching procedure. The density of the glasses increased and the molar volume decreased with increasing BaO concentration. Ultrasonic velocities (VL & VT) increased as the amount of BaO content increased, indicating higher elastic properties. BaO content was found to be the only factor affecting the radiation shielding phenomenon in the glasses. BaO reinforcement not only increased the density of the glass compositions, but also enhanced their mechanical and gamma-ray shielding properties.
