Ultrasonic velocity and density measurements in WO3 – Na2O – P2O5 and WO2-CaO-P2O5 composition glasses have been made at the room temperature by making use of pulse echo overlap method. These values are used to evaluate elastic moduli such as longitudinal, Young’s, bulk and shear moduli, Poisson’s ratio, acoustic impedance, micro hardness, Debye temperature and thermal expansion coefficient. The structural and physical properties of the glass samples have been discussed in the light of the above parameters.
