摘要The exceptional ability of carbon to form sp(2) and sp(3) bonding states leads to a great structural and chemical diversity of carbon-bearing phases at nonambient conditions. Here we use laser-heated diamond-anvil cells combined with synchrotron x-ray diffraction, Raman spectroscopy, and first-principles calculations to explore phase transitions in CaCO3 at P > 40 GPa. We find that postaragonite CaCO3 transforms to the previously predicted P2(1)/c CaCO3 with sp(3)-hybridized carbon at 105 GPa (similar to 30 GPa higher than the theoretically predicted crossover pressure). The lowest-enthalpy transition path to P2(1)/c CaCO3 includes reoccurring sp(2) and sp3 CaCO3 intermediate phases and transition states, as revealed by our variable-cell nudged-elastic-band simulation. Raman spectra of P2(1)/c CaCO3 show an intense band at 1025 cm(-1), which we assign to the symmetric -O stretching vibration based on empirical and first-principles calculations. This Raman band has a frequency that is similar to 20% lower than the symmetric C-O stretching in sp(2) CaCO3 due to the C-O bond length increase across the sp(2)-sp(3) transition and can be used as a fingerprint of tetrahedrally coordinated carbon in other carbonates.
