Figure 3
Two characteristic morphologies of the benzene crystals in phase I: (a) the globular single crystal at ∼ 0.3 GPa and 310 K; (b) a single crystal with well developed faces at about 400 K, growing at isochoric conditions in the DAC after benzene was pressure-frozen at ca 100 MPa at room temperature and then heated to melting, except for one grain. Two ruby chips for pressure calibration are visible at the top and right edges of the DAC chamber. |
