“…Among these, lithium-zinc-silicate (LZS) glass is regarded as an essential system for various applications such as sealing, dental, and dielectrics. This is because, wide thermal expansion range (5 to 20x10 -6 ºC -1 ), ability for glass-ceramic formations, relatively good glass viscosity behavior, high electrical insulation, and considerable density values can be obtained with the use of LZS glasses which in turn possessing great potential for radiation shielding applications [16,17]. Furthermore, calcium oxide (CaO) which has a relatively high density value (3.34 g/cm 3 ) can aid to improve radiation shielding characteristics in the LZS glass system since its positive effect on different glass system has been confirmed by numerous literature studies [18,19].…”

In this study, a preliminary theoretical investigation on lithium-zinc-calcium-silicate (LZCS) glass with a composition of (15-x)Li 2 O-10ZnO-10CaO-65SiO 2 -xB 2 O 3 where x: 0, 3, 6, 9, 12, and 15 mol% was performed to understand the effect of B 2 O 3 on physical, optical, and radiation shielding properties. For this purpose, the L15B0 to L0B15 glass series was designed for evaluating glass density (ρ glass ), refractive index (n), mass attenuation coefficient (µ m ), and half-value layer (Δ 0.5 ) parameters. The theoretical calculations showed that the increasing amount of B 2 O 3 increased the overall ρ glass from 2.9195 to 2.9865 g/cm 3 . Further, the addition of B 2 O 3 in substitution for Li 2 O enhanced the n parameter from 1.6882 to 1.7626. Additionally, BatchMaker software aided to investigate viscosity behavior with the increasing temperature. We found out that the melting point of LZCS glass series ascends with the addition of B 2 O 3 , namely from 1309 to 1624 ºC. On the other hand, the newly developed Phy-X/PSD software computations paved the way for ascertaining µ m and Δ 0.5 . According to the µ m computations, one can clearly state that an increasing trend is observable against the increasing photon energy, but the L0B15 possessed an enhanced shielding ability than that of the remaining at all photon energies. Moreover, we found out that the Δ 0.5 increased with respect to the ascending photon energies, however, the Δ 0.5 was effectively improved with the addition of B 2 O 3 in the order of L0B15
