Abstract
The velocity of longitudinal and transverse ultrasonic waves in four d ifferent compositions of (MoO3)x (TeO2)1-x glass system (x=0.2, 0.3, 0 .45, 0.5) have been measured at room temperature using the pulse echo technique. The velocity data have been used to determine the elastic m oduli, Debye temperature and Poisson's ratio for each composition. The results indicate that the elastic moduli depend upon the composition of the prepared glass.
