Here, the structural stability of fluorite-type La₂Ce₂O₇ was studied at pressure up to ~40 GPa and under hydrothermal conditions (~1 GPa, 350 °C), respectively, using synchrotron x-ray diffraction (XRD) and Raman scattering measurements. XRD measurements indicated that fluorite-type La₂Ce₂O₇ is not stable at pressures greater than 22.6 GPa and slowly transforms to a high-pressure phase. The high-pressure phase is not stable and changes back to the fluorite-type structure when pressure is released. The La₂Ce₂O₇ fluorite is also not stable under hydrothermal conditions and begins to react with water at 200~250 °C. Both Raman and XRD results suggest that lanthanum hydroxide La(OH)₃ and La³⁺-doped CeO₂ fluorite are the dominant products after hydrothermal treatment.
