Figure 1

Patterns were calculated to correspond to a pressure of 7 GPa, and λ=0.3738 Å. The calculated diffraction pattern for α-cristobalite Si0.4C0.6O2 is depicted in blue (lattice dimensions from ref. 5) and the calculated pattern for Pbcn β-ReO2 is represented in black (a=4.7735 Å, b=5.6047 Å and c=4.5755 Å). Calculated Re peaks are shown in red. Vertical dashed lines correspond to the positions of the X-ray diffraction peaks observed at 7 GPa by Santoro et al. (data obtained from a digitized version of Fig. 2 of ref. 5).
