Figure 1

(a) Integrated XRD patterns at different T around 30 GPa and (b) corresponding zoomed region around the XRD diffuse signal. The onset of melting, characterized by the first appearance of the diffuse signal, is observed at 3007 K (orange pattern). The diffuse scattering increases with the rising T, showing its maximum at 3660 K (red pattern). (c–e) unwrapped raw XRD images showing the textural evolution of a Cr sample embedded in KBr pressure transmitting medium at around 30 GPa. The signals arising from the different components are highlighted with different colours: yellow for the Cr and white for the KBr-B2. T is also indicated in red.
