Elastic and Radiation Shielding Properties of Cadmium and Lead-Incorporated Zinc Barium Phosphate Glass

Invert zinc-barium phosphate (ZnO-BaO-P2O5) glass networks were fabricated using the melt-annealing technique. The base glass was modified with cadmium oxide (CdO), lead oxide (PbO), and a mix between CdO and PbO. The elastic parameters were discussed using the Makishima-Mackenzie approach. The calculated values of Young's (E), bulk (B), and shear (S) moduli decreased after the CdO, CdO+PbO, and PbO were introduced to the network from 53.704 to 52.019 GPa, 34.034 to 32.860 GPa, and 23.184 to 22.473 GPa, respectively. XCOM database was used to compute the mass attenuation coefficient (MAC) and estimate the radiation shielding properties of such glasses. For example, the MAC for the base sample at 0.06 MeV was 3.365 cm(2) /g, which rose to 3.554 cm(2) /g for the sample containing PbO. The mean free path (MFP), tenth value layer (TVL), and effective atomic number (Z(eff)) were all discussed. The MFP values depend on the glass composition, which decreased from 0.091 cm (the base sample) to 0.082 cm (the glass with PbO) at 0.06 MeV. The phosphate glass, which contains PbO and CdO+PbO, is more suitable for radiation shielding applications. (c) 2024 The Author(s).
