Abstract: The purpose of this work is to determine the effect of neodymium nanoparticle concentration on the elastic properties of zinc tellurite glass. A series of neodymium nanoparticle doped zinc tellurite glass systems (ndnpszt) were synthesized by traditional melt quenching method. The compositions are [(TeO2) 0.70 (ZnO) 0.30] (Nd2O3 NPs),,,, and. The amorphous properties of the glass system were confirmed by XRD analysis. The density of glass system was measured by Archimedes method. Elastic properties   MHz frequency is calculated according to the density and ultrasonic velocity measured at 5 ℃. The experimental results show that the elastic properties depend on the composition of the glass system and the influence of neodymium nanoparticles (Nd2O3 NPs) in the glass network. increment in ultrasonic velocities is due to the increase in rigidity and change in structural units of the glass system. The softening temperature and the microhardness increased with the increase in Nd3+ ions concentration from 0.1 to 0.2 mol and decreased when the Nd3+ ions concentration increased from 0.2 to 0.5 mol. Poisson’s ratio and Debye’s temperature decreased with the increase in the Nd3+ ions concentration from 0.1 to 0.2 mol and increased when the Nd3+ ions concentration was increased from 0.2 to 0.5 mol.
