Structural, Elastic Moduli, and Radiation Shielding of SiO₂-TiO₂-La₂O₃-Na₂O Glasses Containing Y₂O₃

Quaternary glasses with the chemical composition 50SiO₂-25TiO₂-5La₂O₃- (20-x) Na₂O-xY₂O₃ by use the melt-quench method. The FT-IR spectroscopy investigated the structural change in these glasses. XRD examined the nature of these glasses. While the density is increased, the molar volume of the glass system is reduced. Ultrasonic velocities and elastic modulus of these glasses were experimentally and theoretically calculated based on the Makishima-Mackenzie model. Moreover, the radiation shielding capacity was evaluated for the studied glasses. The mass attenuation coefficient (μ/ρ), half value layer(HVL), tenth value layer (TVL), mean free path (MFP), effective atomic number (Z_eff), electron density (N_eff), equivalent atomic number Z_eq, and effective removal cross section (Σ_R) of prepared glasses were simulated for gamma photon energies between 0.015 and 15 MeV. Exposure build-up factor (EBF) and (EABF) of prepared glasses were evaluated.
