| Post-perovskite |
|
300 K | 164.9 ų Unit cell |
219 | 4 | second-order Birch-Murnaghan | — | Original | ||||||||||||
| Why this differs from similar rows: Birch-Murnaghan fit with K'0 fixed at 4 (main reported fit); sibling row instead fixes K'0 = 4.4 to illustrate parameter tradeoffs. | ||||||||||||||||||||
| Post-perovskite |
|
300 K | 166.2 ų Unit cell |
198 | 4.400 | second-order Birch-Murnaghan | — | Original | ||||||||||||
| Why this differs from similar rows: Text explicitly says this row fixes K'0 = 4.4 'to illustrate the tradeoffs' between correlated V0/K0/K'; sibling row instead fixes K'0 = 4. | ||||||||||||||||||||
| Bridgmanite |

231.900 | 4.400 | unknown | — | Cited | ||||||||||||
| Why this differs from similar rows: Table 1 cites Ref. 5 (Oganov & Ono 2004) LDA result; other rows in this table cite Ref. 5 GGA or a different source, Ref. 24. | ||||||||||||||||||||
| Post-perovskite |
|
— | 167.6 ų Unit cell |
200 | 4.500 | unknown | — | Cited | ||||||||||||
| Why this differs from similar rows: Table 1 cites Ref. 5 (Oganov & Ono 2004) GGA result, a different DFT functional than the LDA value from the same reference in the sibling row. | ||||||||||||||||||||
| Post-perovskite |
|
— | 163.8 ų Unit cell |
215.900 | 4.410 | unknown | — | Cited | ||||||||||||
| Why this differs from similar rows: Table 1 cites a different original study, Ref. 24 (Tsuchiya et al. 2005) LDA, versus Ref. 5 (Oganov & Ono 2004) cited in the other rows. | ||||||||||||||||||||
