Mechanical properties, elastic moduli, and gamma ray attenuation competencies of some TeO2-WO3-GdF3glasses: Tailoring WO3-GdF3substitution toward optimum behavioral state range

Abstract

We report the mechanical properties, elastic moduli, and gamma ray attenuation properties of some TeO2-WO3-GdF3 glasses. Using the chemical composition of the selected glasses, the dissociation energy per unit volume (G t ) and the packing density (V t ) were calculated. Using the G t and V t values, Young's, Shear, Bulk, Longitudinal Modulus, and Poisson's ratio of the glasses are calculated. Next several fundamental gamma ray attenuation properties such as linear and mass attenuation coefficients, half value layer, mean free path, effective atomic number, effective electron density, effective conductivity, exposure, and energy absorption buildup factors are calculated in 0.015-15 MeV energy range. As a consequence of WO3-GdF3 substitution, the glass densities are observed in different values. The overall gamma ray attenuation properties are found to be enhanced through WO3 addition. Moreover, the increasing WO3 incorporation into glass configuration decreases the overall elastic moduli of glasses. It can be concluded that increasing WO3 may be a useful tool for enhancing the gamma ray attenuation qualities and decreasing the elastic moduli of TeO2-WO3-GdF3 in situations where a material with versatile mechanical properties is required. © 2023 the author(s), published by De Gruyter.
