- Abstract
Five glass samples with the following chemical formation: 21.5 SiO
2 -58.5B2 O3 -(20-x) ZnO- xLa2 O3 , where x = 0–10 mol% were fabricated utilizing melt quenching. With an increase in La2 O3 , the glasses' density increased from 3.174 to 4.754 g/cm3 . Experimental data were used to evaluate the mechanical characteristics, and the Makishima and Mackenzie model's semi-empirical methods were used to analyze the elastic properties. As the amount of La2 O3 increases, there's a noticeable rise in the velocity of ultrasonic waves. This heightened velocity is likely linked to the strengthening or increased rigidity of the glass network. Elastic moduli values of the glasses under investigation increase with an increase La2 O3 content. Employing Phy-X/PSD code, the radiation attenuation behaviour of zinc borosilicate glasses with varying La2 O3 concentrations were examined. With increased energy, the enhancement LAC decreases from 2.576 to 0.0375. The ZBSL10 glasses demonstrated strong mechanical and physical characteristics as well as radiation shielding capabilities. The features of the ZBSL glasses are particularly attractive for a variety of mechanical and shielding applications. [ABSTRACT FROM AUTHOR]- Published
