Physical Features of High-Density Barium–Tungstate–Phosphate (BTP) Glasses: Elastic Moduli, and Gamma Transmission Factors

Abstract

We present elastic moduli, gamma radiation attenuation characteristics, and transmission factor of barium–tungstate–phosphate (BTP) glasses with the chemical formula (60-y)BaO-yWO3-40P2O5, where y = 10 (S1)–40 (S4) in steps of 10 mole%. Different types of mathematical and simulation approaches, such as the Makishima–Mackenzie model, the Monte Carlo method, and the online Phy-X/PSD software, are utilized in terms of determining these parameters. The total packing density (Vt) is enriched from 0.607 to 0.627, while the total energy dissociation (Gt) is enriched by increasing the WO3 content (from 52.2 (kJ/cm3). In the investigated glasses, increasing tungstate trioxide (WO3) contribution enhanced Young’s, shear, bulk, and longitudinal moduli. Moreover, Poisson’s ratio is improved by increasing the WO3 content in the BTP glasses. The 20BaO-40WO3-40P2O5 sample possessed the highest values of both linear (µ) and mass attenuation (µm) coefficients, i.e., (µ, µm)S4 > (µ, µm)S3 > (µ, µm)S2 > (µ, µm)S1. Moreover, the 20BaO-40WO3-40P2O5 sample had the lowest values of half (HVL) and tenth (TVL) layers, i.e., (half, tenth)S4 < (half, tenth)S3 < (half, tenth)S2 < (half, tenth)S1. The effective atomic number (Zeff) of the studied glasses has the same behavior as µ and µm. Finally, the 20BaO-40WO3-40P2O5 is reported with the minimum values of transmission factor (TF) for all the BTP investigated at a thickness of 3 cm. In conclusion, the sample with composition 20BaO-40WO3-40P2O5 which has the maximum WO3 reinforcement may be a beneficial glass sample, along with its advanced mechanical and gamma ray shielding properties.

Investigation On Ce3+ Doped Barium Tin Boro-Phosphate Glass for White LED And Nuclear Radiation Shielding Applications

“…The glass samples are amorphous, according to the measurements' analysis. The radical distribution functions are represented by the hump in the XRD spectrum, and the absence of a peak suggests that the glass that was created has a non-crystalline structure [20].…”

“…The two most crucial material properties are their optical and electric conductivities. The following principles may be used to evaluate the optical (σop) and electrical (σe) conductivities of Ce 3+ Doped Barium Tin Boro-phosphate glass [19][20].…”

“…P2O5 glass doped with rare earth elements has high transmittance values. Alkaline oxides are usually added to phosphate glasses to improve their stability and resistivity [5][6][7][8]. The luminescence quantum efficiency and emission transition bandwidth of rare earth element-doped glasses are highly dependent on the choice of host material structure.…”

“…Titanium dioxide's tetravalent, trivalent, and low coordination numbers allow it to modify and enhance the properties of glass, including density and optical absorbance. TiO6 serves as a titanium cation glass modifier and TiO4 as a glass-forming agent [19]. Thus, as a host material, this study investigates the characteristics of Ce 3+ Doped Barium Tin Borophosphate glass.…”
