Spectroscopic and Attenuation Shielding Studies on B2O3-SiO2-LiF- ZnO-TiO2 Glasses

Abstract

Effects of TiO2 addition on the spectroscopic and nuclear shielding properties of lithium fluoride zinc titanate borosilicate glasses with the form 59B(2)O(3)-29SiO(2)-2LiF-(10 - x)ZnO-xTiO(2)x = 0, 2, 4, 6, 8, and 10 mol % labelled as G1-G6, respectively were investigated. The amorphous state of this system was experimentally evaluated using X-ray diffraction. The spectroscopic properties of the recent glasses positively correlated to the increase in TiO2 content. Molar Refractivity (R-m), molar Polarizability (proportional to(m)),reflection loss (R-L), metallization criterion (M), electron Polarizability (alpha degrees), ionic concentration (Ni), titanium-titanium separation (dTi - Ti), inter ionic distance (Ri), inter-nuclear distance (ri), and polaron radius (rp)of the synthesized glasses were determined. Our results show that both the band gap and refractive index increased with TiO2 content while Urbach energy decreased. The nuclear radiation shielding properties of these glasses were explored by utilizing Phy-X/PSD simulations. The lower value of the (MFP) sample contains higher TiO2 content, so good glasses for gamma radiation attenuation are accessible. Fast cross section neutron removal of these glasses enhanced as the concentration of TiO2 increased. Gamma-ray shielding properties of these glasses were compared with different conventional shielding materials and commercial glasses. Therefore, the investigated glasses have potential uses in gamma shielding applications.
