148 | 4.090 | third-order Birch-Murnaghan | — | Original | ||||||
| Why this differs from similar rows: This study's cubic fit to single-crystal data in helium medium, 1.8-55.5 GPa; other rows use neon medium, a different pressure range/structure, or Zhuravlev et al. (2010) data. | ||||||||||||||
| Ferropericlase |
|
300 K | 78.742 ų Unit cell |
163 | 4.020 | third-order Birch-Murnaghan | — | Original | ||||||
| Why this differs from similar rows: This study's cubic-indexed fit in neon medium, low-pressure region (1.3-19.2 GPa) with a strong K' prior; other rows use helium medium, the high-P hexagonal indexing, or literature data. | ||||||||||||||

300 K | 58.7 ų Unit cell |
176.800 | 4 | third-order Birch-Murnaghan | — | Original | ||||||
| Why this differs from similar rows: This study's hexagonal-indexed fit to the same crystal in neon at higher pressure (24.1-53.3 GPa), distinct from the cubic-indexed low-pressure fit and other rows. | ||||||||||||||

166 | 4.010 | third-order Birch-Murnaghan | — | Original | ||||||
| Why this differs from similar rows: Refit of powder XRD data from Zhuravlev et al. (2010) in neon medium (7.9-39.8 GPa), a different original dataset/technique (powder vs. single-crystal) than the other rows. | ||||||||||||||
