| Abstract | This study aimed to examine recycled window glasses' structural and elastic properties (RWG). The recycled window glasses were prepared in the 90RWG 10Na2O xMnO2 system (x = 0.001, 0.01, 0.1, and 1.0 mol %) by the conventional melt quenching method at 1250 ?C. The densities of the glass samples were determined using Archimedes' principle. Elastic moduli, such as longitudinal modulus, shear modulus, Young's modulus, bulk modulus, Poisson's ratio, and microhardness, were calculated using ultrasonic velocity data from the ultrasonic technique. The ultrasonic velocity measured the velocities of the glass samples at a frequency of 4 MHz and room temperature. FTIR spectra were measured in a wave number range of 400 2000 cm-1 to study the structure of the glass samples by FTIR spectroscopy. The results show that the glass structure was changed and could be improved by increasing the concentration of MnO2 in the glass system. Adding MnO2 to the glass network resulted in the formation of SiO4 bridging oxygen and cross-link density in the glass network. These results lead to changes in the elastic moduli of the glass and an increase in the rigidity of the glass structure. The Si-O-Si linkages of the bridging oxygen were verified by FTIR spectroscopy. |
