A detailed study on the physical, mechanical, structural and gamma ray shielding properties of Al2O3–Na2O–SiO2–B2O3–Bi2O3glass system
The density, boron–boron separation, and molar volume of 4Al2O3–12Na2O-(18-x)SiO2-(64-x) B2O3-(2+2x)Bi2O3 (where x = 2, 4, 6 and 8 mol%) are increasing with the addition of Bi2O3. The addition of Bi2O3 results in an open network structure. The elastic moduli decrease from 34.711 to 29.875 GPa for Young modulus (E); 20.395 to 15.843 GPa for bulk modulus (B); from 15.257 to 13.494 GPa for shear modulus (G) and 40.738 to 33.836 GPa for longitudinal (L) respectively with increased Bi2O3 concentration. FTIR spectrainvestigation found BO3, BO4, SiO4, and BiO6 structural units to be present. The glasses' highest mass attenuation coefficient (MAC) is at 0.0395 MeV, the lowest energy value. It gradually decreases as energy increases. There is a decrease in the linear attenuation coefficient (LAC) values with energy. Sample Bi18 has the highest MAC and LAC values due to its high concentration of Bi2O3. Across the entire energy range, sample Bi18 has the highest effective atomic number, and the lowest half value layer and mean free path values across all energy values. The transmission factor (TF) values for Bi6 indicate that the required thickness for blocking 90% of the radiation must be greater than the thickness necessaryfor the attenuation of 50%. Bi18 has the lowest TF compared to other glass samples. The radiation protection efficiency values for Bi18 are highest, confirming their full protection ability. Bi18's is the best choice for radiation shielding.
期刊介绍:
In 1985, the Journal of Science was founded as a platform for publishing national and international research papers across various disciplines, including natural sciences, technology, social sciences, and humanities. Over the years, the journal has experienced remarkable growth in terms of quality, size, and scope. Today, it encompasses a diverse range of publications dedicated to academic research.
Considering the rapid expansion of materials science, we are pleased to introduce the Journal of Science: Advanced Materials and Devices. This new addition to our journal series offers researchers an exciting opportunity to publish their work on all aspects of materials science and technology within the esteemed Journal of Science.
With this development, we aim to revolutionize the way research in materials science is expressed and organized, further strengthening our commitment to promoting outstanding research across various scientific and technological fields.
