Elastic properties of Na2O-B2O3-V2O5 glasses

This paper describes the sound velocity and the elastic properties of Na2O-B2O3-V2O5 glasses over a wide range of composition. Sound velocities (transverse and longitudinal) have been measured using a pulse echo superposition method at a frequency of 10 MHz. The elastic moduli (L, G, K and E), Poisson's ratio (σ) and Debye temperature (θD) exhibit composition dependent trends. The variation of these parameters has been explained using a structural motifs present and the dimensionality of the glass network.
