Description
Summary:Recycled window glass offers a sustainable alternative for glass production. This study investigates the potential for tailoring its elastic and structural properties using Cu2O doping and gamma irradiation. Glasses with varying Cu2O content (0–1.0 mol%) were fabricated via melt quenching and subjected to gamma irradiation (1 kGy). Ultrasonic velocity measurements, elastic moduli calculations, and X-ray diffraction (XRD) analysis revealed a significant strengthening of the network structure with increasing Cu2O content. This strengthening is attributed to the formation of additional bridging oxygen (BO) linkages within the glass network, as confirmed by Fourier Transform Infrared (FTIR) spectroscopy. Conversely, gamma irradiation introduced a weakening effect, reflected in the decrease in elastic moduli. This suggests potential disruption of the network structure, possibly due to the formation of non-bridging oxygen (NBOs). XRD analysis further confirmed the amorphous nature of all glass samples, indicating successful incorporation of Cu2O into the glass matrix. These findings demonstrate the ability to manipulate the properties of recycled window glass using Cu2O and highlight the importance of considering environmental factors like gamma irradiation. •Recycled window glass successfully incorporated into new glass system (90RWG-10Na₂O-xCu₂O).•Ultrasonic/FTIR methods reveal Cu2O/gamma impact on glass structure.•Cu2O incorporation strengthens glass network, evidenced by stronger FTIR peaks.•Gamma irradiation introduces NBOs, weakening glass elasticity.
