The physical, structural and the gamma ray shielding effectiveness of the novel Li2O-K2O–B2O3–TeO2 glasses

Abstract

The purpose of this effort is to create and characterize new borate-based glass samples in terms of their physical, structural, and gamma ray shielding capabilities. The density of the current samples, was examined experimentally and has a range of 2.2057–2.9055 g/cm3. The physical parameters such molar volume, ionic concentration, the volume of boron atoms per mole, optical basicity, and oxygen packing density (OPD) are computed by following the established approach. The XRD spectra is also recorded and there are two broad humps which shows that the structure of fabricated glasses is amorphous in nature. Moreover, the FTIR spectra were recorded in the spectral range 1600–400 cm−1. Using the Phy-X/PSD online tool, the gamma ray shielding capabilities of the manufactured glasses were examined. At the highest energy, LiKBTe0 has mass attenuation coefficient (MAC) equal to 0.039 cm2/g and LiKBTe20 has a MAC equal to 0.038 cm2/g. At 0.347 MeV, the LiKBTe20 sample has effective atomic number (Zeff) of 11.67 and the LiKBTe0 sample has a Zeff of 7.85, which is due to Te’s much greater atomic number compared to B. Half value layer (HVL) increases with increasing energy. When considering which glass best boosts shielding qualities, 10 Li2O- 20 K2O − 50 B2O3 – 20TeO2 glass comes out on top.
