Using the melt-quenching process, a new set of scandium-doped lithium aluminum borate glasses with the chemical formula 70B2O5 − 20Li2O − (10 − x) Al2O3 − xSc2O3 were created. X-ray diffraction was used to confirm that the resulting glasses were amorphous. The functional groups present in glass network were investigated using FT-IR spectrometer. The Makishima–Mackenzie theoretical model was used to assess the glass elastic properties. These findings demonstrated a direct relationship between the scandium ion concentration and the elastic moduli, which include the Shear modulus, Bulk modulus, Young's modulus, and Poisson's ratio. Studies on the radiation shielding capabilities of glasses modified with Sc2O3 have shown that at higher concentration Sc2O3 exhibits the better shielding characteristics. The concentration-dependent linear attenuation coefficient, which resulted in lower half-value layer values are noteworthy. These results imply that adding Sc2O3 is essential for increasing the glass's shielding effectiveness.
