摘要: Abstract In this work, the effect of BaO on optical, physical and radiation shielding properties SiO2-15B2O3-2Al2O3- 10CaO-23Na2O glasses have been investigated. Glasses in composition (50-x)SiO2:15B2O3:2Al2O3:10CaO:23Na2O: xBaO, where x = 0, 5, 10, 15 20% mol were fabricated by melt-quenching technique. The results found that, density molar volume increased with increasing concentration. optical spectra measured uv-visible spectrophotometer show shifted to longer wavelength. Gamma-ray at 662 keV SiO2-B2O-2Al2O3-10CaO-23Na2O-BaO studied. experimental showed good agreement theoretical values, calculated WinXCom. Moreover, comparison ordinary concrete commercial window term half value layer has investigated better advantage being transparent visible light. From calculation, Compton scattering gives dominant contribution total mass attenuation coefficients for all studied glass samples.
