The influence of MgO on the radiation protection and mechanical properties of tellurite glasses

摘要: Abstract Mechanical moduli, such as Young’s modulus (E), Bulks (B), Shear (S), longitudinal (L), Poisson’s ratio (σ) and micro Hardness (H) were theoretically calculated for (100-x)TeO2+x MgO glasses, where x = 10, 20, 30, 40 45 mol%, based on the Makishima–Mackenzie model. The estimated results showed that mechanical moduli microhardness of glasses improved with increase contents in TM while decreased content. Moreover, radiation shielding capacity was evaluated studied glasses. Thus, linear attenuation coefficient (LAC), mass (MAC), transmission factor (TF) half-value thickness (Δ0.5) simulated gamma photon energies between 0.344 1.406 MeV. glass TM10 10 mol % possess highest LAC varied range 0.259 0.711 cm−1, TM45 45 mol lowest vary 0.223 0.587 cm−1 at Furthermore, BXCOM program applied to calculate effective atomic number (Zeff), equivalent (Zeq) buildup factors (EBF EABF) removal cross-section fast neutrons (ERCSFN, ∑R) also theoretically. received data depicts ∑R achieved ∑R = 0.0193 cm2 g−1, possesses ERCSFN ∑R = 0.0215 cm2 g−1.
