— | — | 150 | 4 | third-order Birch-Murnaghan | — | Original | ||||
| Why this differs from similar rows: K0 derived using the (200) reflection alone for volume, preferred by authors due to anisotropic broadening under slightly non-hydrostatic conditions; sibling row uses 3 reflections. | ||||||||||||
| Wüstite |
|
— | — | 167 | 4 | third-order Birch-Murnaghan | — | Original | ||||
| Why this differs from similar rows: K0 derived using (111)+(200)+(220) reflections combined for volume; differs from sibling row's (200)-only approach due to anisotropic broadening from non-hydrostatic conditions. | ||||||||||||
