摘要Pressure-related structural properties of CaCrO4 with zircon-type structure (14(1)/amd) at ambient pressure were investigated using synchrotron radiation x-ray diffraction in energy-dispersive mode in a diamond anvil cell (DAC) up to 29.1 GPa at room temperature. A sluggish first-order structural phase transition to a scheelite-type phase (14(i)/a) was observed at 5.7 GPa. The lattice parameters of both phases at different pressures were calculated. The isothermal Birch-Murnaghan equation of state (EOS) was used to fit the data of pressure versus unit cell volume, and the bulk moduli were simulated to be 103.7 +/- 0.3 and 125.1 +/- 6.2 GPa for the zircon and scheelite phase, respectively.
