- Abstract
This study examines the physical, optical and mechanical characteristics of BWP glasses. The density and molar mass increase as the WO3 concentration rises, resulting in a denser and more substantial glass sample. However, the molar volume decreases, indicating a reduction in volume due to the increased density caused by WO3. The inclusion of WO3 also leads to a tighter spacing between atoms. The optical basicity of the glass increases with higher WO3 concentrations. The electronegativity decreases, suggesting the glass becomes more electron-donating. The electronic polarizability and cross-link density increase, resulting in a stiffer and more robust glass network. The mechanical moduli, including Young's modulus, bulk modulus, shear modulus, and longitudinal modulus, also increase with higher WO3 concentrations, indicating improved mechanical characteristics and reduced deformation. The Poisson's ratio shows a larger transverse deformation tendency with increasing WO3 concentration. Micro-hardness values increase with WO3 content, indicating enhanced durability and mechanical robustness. The mean free path values indicates that the higher WO3 content, or lower P2O5 content, improves the shielding ability.
