Compressional (VP) and shear wave (VS) velocities of the amorphous phase of ZrW2O8 have been measured up to 10.4 GPa at room temperature using ultrasonic interferometry in conjunction with synchrotron x radiation. The pressure-density relation is determined using the measured velocities. Both VP and VS, as well as the adiabatic bulk and shear moduli, exhibit monotonic increase with increasing pressure. The pressure derivatives of the bulk and shear moduli are determined to be KS0'=7.3(1) and G0'=1.8(1), with bulk and shear moduli KS0=61.7(5) GPa and G0=35.0(2) GPa. Comparing with the a phase, VP, VS, KS0, E, Tac, and s of the amorphous phase decrease by 14.8%, 10.0%, 17.2%, 2.9%, 1.2%, and 15.5%, along with 28% and 3.2% increase in density and shear modulus, respectively.
