(a) Cell assembly containing the three pairs of PT calibrants, CsCl–Pt, KCl–Re and KBr–Mo and thermocouple. (b) X-ray radiograph showing the samples in situ at high PT conditions. (c) Representative energy-dispersive XRD patterns of selected calibrants at the indicated conditions. Fluorescence lines, including those from the Pb shielding of the detectors, are indicated by asterisks (*). MgO peaks from the pressure medium can be identified. |
