Study on ultrasound velocities and elastic properties of sodium diboro-vanadate glasses

Glasses with general formula xNa2O-15V2O5-(85-x)B2O3 where x is varied from 5 to 50 mol% in steps of 5 mol%, are fabricated using melt quenching technique. Ultrasound velocities, elastic moduli and Poisson's ratio exhibit composition dependent trends. Both ultrasound velocities and elastic modu...

Description
Summary:Glasses with general formula xNa2O-15V2O5-(85-x)B2O3 where x is varied from 5 to 50 mol% in steps of 5 mol%, are fabricated using melt quenching technique. Ultrasound velocities, elastic moduli and Poisson's ratio exhibit composition dependent trends. Both ultrasound velocities and elastic moduli increases with the addition of Na2O mol% whereas Poisson's ratio decreases. The introduction of V2O5 results in the formation of diboro-vanadate units similar to that of a diborate. Formation of these diboro-vanadate units leads to a monotonic increase in both sound velocities and elastic moduli.
