Effect of Bi2O3 on Elastic Properties of Silica Bismuthate Glasses by Pulse–Echo Method

P. Vasantharani, I. Sankeeda

Abstract :

A binary glass system of xBi2 O3  (100–x)SiO2  with x= 60, 65, 70, 75 and 80 mol% was synthesized by rapid melt quenching method. Longitudinal and shear ultrasonic velocities were measured at room temperature us ing pulse–echo method at 5 MHz frequency. The densities of the glasses were also measured by Archimedes principle. Elastic moduli, Poisson’s ratio, Debye temperature, softening temperature, acoustic impedance, thermal expansion coefficient and micro hardness have been calculated from the measured density and ultrasonic velocity. The above parameters were analysed in terms of structural changes of glasses with composition. The results indicate that the elastic moduli and other parameters of the binary glass system decrease with increasing Bi2 O3  content.
