Representative volume–pressure relations for compounds in the post-perovskite (CaIrO3-type) structure.

Thomas S Duffy Phil. Trans. R. Soc. A 2008;366:4273-4293


Selected pressure–volume compression data for perovskite (open triangles (dashed line), En100 (Fiquet et al. 2000); open circles, En91Fs09 (Shieh et al. 2006)) and CaIrO3-type (filled squares,

En100 (Ono et al. 2006); filled diamonds, En100 (Guignot et al. ...



Bulk moduli of Fe-bearing perovskite and CaIrO3-type post-perovskite calculated from EOS fits (Shieh et al. 2006) and compared with density functional theory calculations for MgSiO3 (Oganov

& Ono 2004).



Inverse pole figures from deformation experiments on CaIrO3-type post-perovskites with compositions (a) (Mg,Fe)SiO3 (157 GPa, 300 K; Merkel et al. 2007), (b) MgGeO3 (130 GPa, 300 K;

Merkel et al. 2006) and (c) CaIrO3 (6 GPa, 800 K; Miyagi et al. 2008).



Crystallographic b/a ratio for selected post-perovskites from figure 1.



Average bond lengths from single-crystal X-ray diffraction, powder X-ray diffraction analysed by the Rietveld method and theoretical studies of ABX3 post-perovskites and other phases.



Molar volume difference between the liquid and the solid normalized to molar volume of the solid for MgSiO3 and MgO liquids from recent first-principles simulations.
