Fabrication of newly developed tungsten III-oxide glass family: Physical, structural, mechanical, radiation shielding effectiveness

Abstract

A series of glasses based on the nominal composition of (Na2O)5 + (Al2O3)10 + (SiO2)(85+x)/2 + (CaO)(85+x)/2 + (WO3)x glasses system were produced utilizing the usual melt quenching process in this study. Experimental techniques and the FLUKA Monte Carlo algorithm were used to examine the properties of silicon-calcium glasses containing tungstate-III-oxide. For five glass structures identified according to (Na2O)5+(Al2O3)10+(SiO2)(85+x)/2+(CaO)(85+x)/2+(WO3)x (0 ≤x ≤ 20 wt-%) glass composition, the impact of tungstate-III-oxide with ratios of (0 ≤x ≤ 20 wtpercent) on radiation shielding characteristics of glasses was set. The densities of the produced glasses fluctuated between 2.847 g/cm3 and 3.122 g/cm3 when tungstate-III-oxide was substituted. The produced sample densities, which are important in assessing radiation shielding features, rose as the WO3 concentration increased, according to our first results. In addition, the structure of each sample was studied using FT-IR. FT-IR showed that when WO3 levels rose, the connection level increased, and the FT-IR spectra shifted to higher wavenumbers. The synthesis of WO3 in a glass matrix enhances the structural network by raising oxygen levels, which leads to the transition of SiO2 into - CaO. Elastic moduli and Ultrasonic velocities were found to rise as the ratio of WO3 in the generated samples increased. These two approaches were used to model linear and mass attenuation coefficients, photons-transmittance versus photon energy, radiation protection efficiency against photon energy, and absorber thickness (experimental and simulation). Based on the results, it can be stated that the w20 sample, which contains 20 wt%, will play the most effective function in radiation shielding. Increases in WO3 led in considerable increases in linear and mass attenuation coefficient values, which directly contribute to the development of the glass's radiation shielding characteristics.
