説明
We report in situ high-pressure Raman spectroscopic study of katoite in a diamond-anvil cell under hydrostatic conditions from 1.3 to 8.3 GPa at room temperature. Three Raman bands at 332, 537 and 3652 cm-1 were observed continuously up to 8.3 GPa. The most striking characteristic was that above 5.1 GPa the pressure derivative of the O-H stretching vibration of F2g symmetry started to decrease significantly. The result leads to a proof that the phase transition of katoite to the high-pressure phase occurs at around 5 GPa.
