Synthesis of Pb3O4-SiO2-ZnO-WO3 Glasses and their Fundamental Properties for Gamma Shielding Applications

Abstract

In this research, we prepared zinc lead silicate glass system with the composition 35Pb3O4-60SiO2-(5-x) ZnO-xWO3 (0 ≤ x ≤ 5 mol %) via the melt-quench method. XRD is explored the nature of the glass system. Ultrasonic velocity, and elastic modulus were experimentally investigated and then the results were confirmed by using the theoretical calculations. It was found that because of molar volume reduction inter-ionic distance , polaron radius , and internuclear distance, of the investigated glasses are reduced with WO3 content. The basic attenuation factors; mass and linear coefficients denoted by µ/ρ and µ, respectively, were determined employing several simulations for each energy via FLUKA code. As WO3 content increased from 0 to 5 mol %, the µ increased from 0.728 cm -1 to 0.856 cm -1 achieving high shielding performance for the sample with x = 5 mol %. At 0.6 MeV with x = 5 mol %, we found that the dose rate of the prepared glass system decreases from 2.35 × 10 7 R/h at 1 mm to 4.71 × 10 6 R/h at 4 mm. The values of MFP and HVL are lower than those of the conventional photon shields indicating that our prepared glass samples (especially G5 glass sample) have promising shielding properties to use for x/gamma rays applications.

Investigation of BaO reinforced TiO2–p2O5–li2O glasses for optical and neutron shielding applications

“…Because of the pair creation interaction, the (Z eq ) value decreases at energies higher than 1 MeV. [36][37][38][39][40][41][42][43][44][45] As a result, glass with a higher BaO content has a higher Z eq than others. In all photon energy, it was discovered that G 5 has the maximum values, while G 1 has the smallest.…”

“…As a result, the EBF and EABF variance behaviors are primarily impacted by the three main interaction mechanisms discussed previously. [38][39][40][41][42][43][44][45] Fig. 15 Equivalent atomic number for glasses.…”

“…The glass sample G 5 is the best choice for neutron attenuation applications. [38][39][40][41][42][43][44][45]…”

Chemically Synthesized ZnO-WO3 Nanoparticles as Electron and Hole Transport Layer in Organic Solar Cells

“…These include semiconductor gas devices, gas sensors, solar energy devices and photocatalysts (29,30). A new material that combines the advantages of two separate materials, ZnO-WO 3 nanocomposites, has been produced by researchers, so that they can combine their advantages to achieve the ultimate qualities (31,32). Consequently, the ZnO-WO3 nanocomposite system is an interesting platform for a wide range of applications because of the synchronized energyband arrangement between WO 3 and ZnO (33)(34)(35)(36).…”

Effect of CeO2 /Er2O3 co-doping on spectroscopic properties of zinc fluoroborate glasses

“…Heavy metal oxides like ZnO, MoO 3 , and PbO, enhance the chemical durability of glass when incorporated into a glass matrix [11][12][13][14][15]. Zinc is a distinctive TM however it cannot produce glass on its own but can produce stable glasses when mixed with glass-forming oxide.…”
