摘 要：Phase egg(AlSiO3 OH), an important hydrous phase in the Al2 O3-SiO2-H2 O ternary system, was found in the superdeep diamond from the transition zone. Here we have investigated the compressibility and the crystal structural evolution of phase egg using the synchrotron-based single-crystal X-ray diffraction and infrared spectroscopy combined with diamond anvil cells up to 32 GPa and 900 K.
