Abstract

This paper describes the sound velocity and the elastic properties of Na(2)O-B(2)O(3)-V(2)O(5) 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 (sigma) and Debye temperature (theta(D)) exhibit composition dependent trends. The variation of these parameters has been explained using a structural motifs present and the dimensionality of the glass network. (C) 2008 Elsevier B.V. All rights reserved.
