Ultrasonic and Spectroscopic Studies on Structural Elucidation of Some Vanadium Glasses
S. Thirumaran and J. Earnest Jayakumar

Abstract:
Semi conducting vanadium glasses with different V2O5 contents have been prepared by rapid quenching technique. Ultrasonic velocities measurements have been performed over a wide range of temperatures from 1020-1060 K. Elastic moduli, Debye temperature and poisson’s ratio have been obtained for different V2O5 contents as a function of temperature. The composition dependence of velocities show a monotonic variation with the addition of V2O5. Ultrasonic velocity measurements (longitudinal and shear velocities) were carried by using pulse-echo technique at 5 MHz frequency showing that the ultrasonic velocity and the glass density are sensitive to the glass composition and behave identically to each other. The results indicate that the longitudinal wave velocities, shear wave velocities and elastic moduli show the same trend with composition. The X-Ray Diffraction spectral (XRD) studies have been employed to ascertain the amorphous nature of the glass specimen. To identify the functional groups present in the glass samples and to study about the morphology of the glass samples, the prepared glass samples are subjected to optical studies like FT-IR spectroscopy and Scanning Electron Microscopy (SEM), respectively. Eventually the results are discussed with a view to establish the structural characterization, compactness and mechanical properties of the glass samples.
