300 K | 86.71 ų Unit cell |
143 | 5.800 | Birch-Murnaghan (order unspecified) | — | Original | ||||||||||
| Why this differs from similar rows: Main-text fit: V0 fixed at 86.71 A^3, K_T0 and K_T0' both fitted freely from the room-T P-V-T data, yielding K_T0=143(4), K'=5.8(6); sibling Table 1 rows instead fix K0 or fit it differently. | ||||||||||||||||||

300 K | 86.71 ų Unit cell |
143 | 5.850 | Birch-Murnaghan (order unspecified) | — | Original | ||||||||||
| Why this differs from similar rows: Table 1 row where K (=143) is fixed alongside V0 ('the value was fixed when calculated') and only K' (5.85) and thermal terms are fitted; sibling row instead lets K float (=142, K'=6.0). | ||||||||||||||||||
| Phase D |

300 K | 86.71 ų Unit cell |
142 | 6 | Birch-Murnaghan (order unspecified) | — | Original | ||||||||||
| Why this differs from similar rows: Table 1 row where K is fitted freely (=142(3), K'=6.0(5)) rather than fixed; sibling rows fix K (and V0) and only fit K' and thermal terms. | ||||||||||||||||||

300 K | — | 148 | 4.700 | unknown | adiabatic | Original | ||||||||||
| Why this differs from similar rows: Table 1 2-D linear fit over 0-21 GPa at 300 K only; sibling row fits the same model over a wider range (0-23 GPa, 300-900 K) that adds a temperature dependence. | ||||||||||||||||||
| Phase D |
|
300 K | — | 147 | 4.700 | unknown | adiabatic | Original | ||||||||||
| Why this differs from similar rows: Table 1 2-D linear fit over 0-23 GPa and 300-900 K (includes a dK/dT term); sibling row fits only the room-temperature data (0-21 GPa, 300 K). | ||||||||||||||||||

144 | 5.500 | finite strain (unspecified form) | P-scale free · adiabatic | Original | ||||||||||
| Why this differs from similar rows: Table 1 finite strain (pressure-scale-free) fit over 0-21 GPa at 300 K only, V0 fixed; sibling rows fit the same form over the wider 0-23 GPa/300-900 K range with different parameters fixed vs free. | ||||||||||||||||||
| Phase D |
|
300 K | 86.71 ų Unit cell |
144 | 5.500 | finite strain (unspecified form) | adiabatic | Original | ||||||||||
| Why this differs from similar rows: Table 1 finite strain fit over 0-23 GPa/300-900 K with K, K', G0, G' all fixed ('the value was fixed when calculated'); sibling rows in the same range instead let some of these parameters float. | ||||||||||||||||||
| Phase D |
|
300 K | 86.71 ų Unit cell |
144 | 5.550 | finite strain (unspecified form) | adiabatic | Original | ||||||||||
| Why this differs from similar rows: Table 1 finite strain fit over 0-23 GPa/300-900 K with K' fitted freely (=5.55) while K0 stays fixed; sibling rows either fix K' too or let both K0 and K' float. | ||||||||||||||||||
| Phase D |

300 K | 86.71 ų Unit cell |
134 | 6.600 | finite strain (unspecified form) | adiabatic | Original | ||||||||||
| Why this differs from similar rows: Table 1 finite strain fit over 0-23 GPa/300-900 K with both K0 and K' fitted freely (K=134(7), K'=6.6(7)); sibling rows in the same range fix K0, K', or both instead. | ||||||||||||||||||

143.600 | 5.590 | finite strain (unspecified form) | adiabatic | Original | ||||||||||
| Why this differs from similar rows: Table 1 finite strain fit over 0-23 GPa/300-900 K, final row reported without uncertainties (K=143.6, K'=5.59); differs slightly from other same-range rows that fix or float K0/K' differently. | ||||||||||||||||||
