X-ray diffraction and Mössbauer spectroscopy were employed to investigate structural stability of Fe2TiO4under high pressure. Measurements were performed up to about 24GPa at room temperature using diamond anvil cell. Experimental results demonstrate that Fe2TiO4undergoes a series of phase transitions from cubic (Fd3̄m) to tetragonal (I41/amd) at 8.7GPa, and then to orthorhombic structure (Cmcm) at 16.0GPa. The high-pressure phase (Cmcm) of Fe2TiO4is kept on decompression to ambient pressure. In all polymorphs of Fe2TiO4, iron cations present a high-spin ferrous property without electric charge exchange with titanium cations at high pressure supported by Mössbauer evidences.
