We report high-pressure synchrotron X-ray powder diffraction data for the W-rich cubic ZrW2-xMoxO8 (x=0.4) up to 10 GPa with open decompression. This study shows that cubic-ZrW1.6Mo0.4O8 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 ZrW2-xMoxO8 (x=0.4) solid solutions are more attractive for creating products working under extreme conditions and mechanic stress.
