Glasses of the system 60B2O3-(40-x)MnO2-xZrO2 (where x= 0, 5, 10, 15, 20 mol. %) have been prepared by the rapid melt quenching method. The density of each glass samples were determined using Archimedes method with water as a floatation medium. The molar volume have been estimated and analysed for the present study of manganese borate glasses added with zirconium oxide. Ultrasonic velocities, both longitudinal and transverse have been measured using the pulse-echo method at a frequency of 4MH¬z at room temperature. The elastic moduli, Poisson’s ratio, acoustic impedance, microhardness and Debye temperature have been calculated from the measured data. The sound velocity, density, elastic moduli, acoustic impedance, microhardness and Debye temperature increase with increasing ZrO2 concentration. Poisson’s ratio decreases with increasing ZrO2 concentration. The variation of these parameters have been explaining using structural modify present and the dimensionality of the glass network.
