Pressure induced phase transition of hexagonal Zn{sub 0.854}Cu{sub 0.146}O is studied by using synchrotron angle dispersive X-ray diffraction (ADXRD) up to 43.1 GPa at room temperature. A structural transformation from a hexagonal phase to a cubic phase is observed, which starts at 10.2 GPa and finishes at about 16.5 GPa. The phase transition leads to a volume collapse of 17% at 10.2 GPa. The cubic phase of Zn{sub 0.854}Cu{sub 0.146}O remains stable up to the highest experiment pressure. The pressure-volume data are fitted with the Birch-Murnaghan equation of state. The bulk modulus obtained upon compression from the fitting are 175(2) and 259(6) GPa for the hexagonal and cubic phases, respectively.
