Density and Elastic Behaviour of Ternary Tellurite Glass Systems – A Short Review

Abstract

This short review paper presents the elastic properties of various ternary tellurite glass systems prepared using the conventional melt-quenching technique. Their density (ρ), molar volume (Vm) values were calculated from the characterizations data obtained for the interpretation of physical, and elastic properties of the glass system under study. Ultrasonic pulse-echo technique carried out at room temperature, and at resonating frequency of 5 MHz was used for the determination of the ultrasonic velocities (longitudinal and shear). Elastic (longitudinal, shear, bulk and Young’s) moduli, Poisson’s ratio, Debye temperature, and a softening temperature of all glass samples have been estimated using the measured ultrasonic velocities and densities. Experimental data shows that most of the elastic moduli of the ternary glasses were found to be composition dependent.
