Abstract

A novel glass system with the composition 50SiO₂–(48 + X) Na₂B₄O₇–(2 − X) MnO₂ (0 ≤ X ≤ 2 mol%) was synthesized using the classical melting method. The obtained FT-IR spectroscopy of the fabricated samples refers to the transformation of the structural unit BO₃ into BO₄. Ultrasonic velocities and elastic moduli were found to increase with the increase in the ratio of Na₂B₄O₇ in the fabricated samples. MCNP-5 code was applied to determine the gamma-ray shielding characteristics. The results demonstrate that the glasses without MnO₂ content have the best gamma-ray shielding capacity. The linear attenuation coefficient (LAC) varied in the range between 0.055 and 8.873 cm⁻¹ for gamma photons between 0.015 and 15 meV. Moreover, the fast neutron removal cross section was calculated theoretically. The mass stopping power and the projected range were calculated using the Stopping and Range of Ions in Matter program (SRIM) for charged protons and alpha particles.
