Fig. 1

Data acquired during the Pv to pPv transformation at 129.5 GPa and 1700 K (Sample #1 in Table 1). Miller indices of most diffraction lines of Pv (blue), pPv (red) and the Argon pressure medium (Ar, black) are indicated on the figure. Stars indicate diffraction lines that are not assigned to either phase and do not change during the transformation. Weight proportions of pPv relative to the (Pv \(+\) pPv) assemblage are obtained by a Rietveld refinement with the Maud software60. 2\(\theta\) angle ranges with Ar peaks were ignored in the refinements.
