Figure 2 Stages of the HA single-crystal growth inside the DAC chamber (polarized-light mode): (a) one crystal seed at 295 K and 0.33 GPa, (b)/(c) the single-crystal growth with increasing pressure and a simultaneous decrease in the volume of the high-pressure chamber, and (d) the single crystal filling the DAC chamber at 295 K and 0.50 GPa. The ruby chip, for pressure calibration, is located by the left edge of the DAC. |
