Physical properties and gamma radiation shielding capability of highly dense binary bismuth borate glasses

摘要: Abstract Dense glasses in the binary bismuth-borate system, xBi2O3-(1-x)B2O3 (BBO), x = 0.25, 0.5, & 0.75 were prepared by conventional melt-quenching process at different temperatures. The melt was hot pressed between stainless-steel plates to obtain dense glasses. obtained optically clear, thermally stable and amorphous nature. Transparent BBO exhibited high density range of 5.5–8.29 g/cm3 which is attributed bismuth content pressure induced compaction temperatures hot-pressed quenching. Gamma radiation shielding properties investigated calculating mass attenuation coefficients, effective atomic number, buildup factors. Radiation calculated using XCOM Phy-X web software as a function photon energy for all Experimental mass-attenuation coefficients energies determined through transmission method. Measured close agreement with values. Further, exposure absorption factors studied penetration depths energy. results compared heavy-metal oxide reported literature respect lead metal shield. glass low half-value layer, mean-free path are comparable lead. borate here can be excellent transparent simple system promising radiological applications.
