Figure 1
The phase II CH2BrCl single-crystal growth stages from the grain (a) at 430 K to the crystal-filling whole volume of the high-pressure chamber at 1.72 GPa/295 K (d). The Miller indices of the crystal faces have been indicated in (b). The ruby chip for pressure calibration (Barnett et al., 1973; Piermarini et al., 1975) is at the bottom-left (at 8 o'clock) edge of the chamber. |
