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

Quaternary glasses with the chemical composition 50SiO(2)-25TiO(2)-5La(2)O(3)- (20-x) Na2O-xY(2)O(3) 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 (mu/rho), 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 (sigma(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.

Automated summary

The study focused on quaternary glasses prepared using the melt-quench method, investigating their structural changes and properties, including increased density and reduced molar volume, as well as experimentally and theoretically calculated ultrasonic velocities and elastic modulus. Evaluation of radiation shielding capacity was also conducted for the studied glasses.
