We report high-pressure synchrotron X-ray powder diffraction data for the W-rich cubic ZrW 2-x Mo x O 8 (x=0.4) up to 10 GPa with open decompression. This study shows that cubic- ZrW 1.6 Mo 0.4 O 8 transforms to orthorhombic phase at the 5.04 GPa. Pressure-induced reversable amorphization of material was observed at 8.13 GPa. The obtained data suggest that W-rich cubic ZrW 2-x Mo x O 8 (x=0.4) solid solutions are more attractive for creating products working under extreme conditions and mechanic stress.
