摘要

This study focuses on the properties of novel glass compositions containing As2O3, V2O5, Fe2O3, and CaO, which lack traditional glass-forming oxides. Differential Scanning Calorimetry (DSC) analysis revealed enhanced glass-forming ability and thermal stability due to V2O5 substitution for As2O3, attributed to increased terminal oxygen atoms. Mössbauer Effect (ME) spectroscopic analysis indicated ferric ions’ tetrahedral configurations, where higher V2O5 content improved homogeneity. Radiation shielding properties were evaluated using Phy-X/PSD software, with parameters like mass attenuation coefficient (MAC), half-value layer (HVL), and mean free path (MFP) analyzed across gamma energies (0.015–15 MeV). Results showed superior attenuation performance for high-energy photons, with As-rich glasses demonstrating better shielding efficacy due to higher effective atomic number (Zeff). The G-P method was employed for buildup factors (EBF and EABF), confirming As-rich glasses’ suitability for radiation shielding applications in medical and technological fields.
