Abstract: High pressure Energy dispersive X-ray diffraction of BeO has been studied in Beijing Synchrotron Radiation Facility (BSRF) . BeO remain hexagonal Wurtzite structure as ambient pressure phase when pressure from ambient pressure up to 42GPa, no phase transition occur, the cell volume decrease as pressure increase. The data of the Wurtzite phase ranging from 0.6 to 42GPa were fitted to the Murnaghan P-V equation of state. Assume K0' to be 4 and obtained bulk modulus K0=276GPa.
