Abstract：
The high pressure diffraction study of SrF₂ was performed using synchrotron radiation energy dispersive X-rays diffraction (EDXD). Liquid Ar was used as pressure transmitting medium in the experiment in order to produce hydrostatic pressure. The highest pressure was up to 44.2GPa. A phase transition of SrF₂, from cubic to orthorhombic，occurred around 11.2GPa. By fitting the pressure-volume data, the bulk modulus of the cubic phase of SrF₂ is 70.0(5.0)GPa, and the bulk modulus of the orthorhombic of SrF₂ is 198.3(15.2)GPa. SrF₂ was returned to the cubic phase by decreasing pressure.
