Comparative studies between theoretical and experimental of elastic properties and irradiation effects of soda lime glasses doped with neodymium oxide

• Results show good agreement between experimental and theoretical of elastic moduli.
• Network bonding was distorted with the Nd2O3 was added and irradiated.
• Transformation of the glass network structure from Q4Q4 to Q3Q3 after irradiation.

A comparative studies on the theoretical and experimental values of elastic moduli of (90−x)RWG−(10)Na2O−(x)Nd2O3(90−x)RWG−(10)Na2O−(x)Nd2O3 glass system, where RWG is recycled window glass and xx is 0.001, 0.01, 0.1 and 1 mol%, was investigated. The radiation effects on structural properties and elastic moduli were evaluated by measuring the ultrasonic velocities. In addition, the FTIR spectra were measured to investigate the effects of irradiation on the structure of the glass. Moreover, the theoretical bond compression model was used to confirm the obtained results from the experiments. The results show that evidently changes in the structure of the glass depend on the concentration of the neodymium oxide and gamma irradiation. Furthermore, the experimental elastic moduli are in good agreement with the theoretical values.
