Fig. 9: Differences of experimentally obtained g(r) between 850 and 700 K at 5.5 GPa and between 870 and 850 K at 5.5 GPa.

a Difference of g(r) before (700 K) and after (850 K, HPQ) the structural change at 5.5 GPa. b Difference of g(r) between the samples treated at 870 K (pHPQ) and 850 K (HPQ) at 5.5 GPa. Arrows indicate enhanced distances at high temperatures at 5.5 GPa.
