Tailor made barium borate doped Bi2O3 glass system for radiological protection

The study presents a ternary glass series fabricated as a mixture of 60B2O3-(40-x)BaO-xBi2O3, x = 0, 2.5, and 5 wt %. The glass density was measured using the Archimedes method with Xylene as an immerse liquid. The fabricated glass samples' mechanical features and elastic moduli were evaluated utilizing the MakishimaMakenzie (M-M) model based on the fabricated glass chemical composition and density. The elastic moduli were varied in the range between 92.862 and 99.734, 71.142-81.750, 36.208-38.457, and 119.420-133.027 Gpa for Young, bulk, shear, and longitudinal moduli. Other mechanical properties like Poisson ratio, microhardness, fractal bond conductivity, and softening temperature were predicted based on the fabricated glass samples' elastic moduli. Moreover, experimental measurements were applied to evaluate the linear attenuation coefficient at energies 662, 1173, and 1332 keV. The experimental measurements were confirmed with the theoretical XCOM program. Monte Carlo N- particle transport code version 5, XCOM, and BXCOM programs were used to evaluate the fabricated glass samples' radiation shielding properties.

Automated summary

The study fabricated a series of ternary glasses and predicted the mechanical properties and elastic moduli of the glass samples using experimental measurements and models.
