A series of glasses xPr6O11-(35-x) Ag2O-65B2O3 (x=0, 0.1 to 0.5 mol %) were synthesized by melt quenching technique. The absence of any crystalline peaks in the X-ray diffraction patterns of the present glass samples indicates the amorphous nature. Longitudinal and transverse ultrasonic velocities were measured at 5 MHz frequency and at room temperature. Elastic properties, Poisson’s ratio, Debye temperature, micro hardness and glass transition temperature have been calculated from the measured density and ultrasonic velocity. The variations of these parameters have been discussed with respect to Praseodymium oxide concentration.
