Abstract

Abstract: The effects of addition of Bi2 O3 to borate glasses in a series of (75-x) B2 O3 -xBi2 O3 -10Na2 O-10CaO-5Al2 O3 have been studied through the ultrasonic properties of the glasses. The ultrasonic wave velocities (longitudinal, VL and shear, VS ) were measured at 4 MHz using ultrasonic pulse echo method. Longitudinal L, shear G, bulk K, Yong's E moduli, Poisson's ratio σ, Microhardness (H), softening temperature (Ts ) and Debye temperature (θD ) were measured. Quantitative analysis of the experimental data has been carried based on the bond compression and Makishima-Mackenzie models.
