Iron density/pressure diagram

Geophysicists have spent considerable efforts to develop experimental techniques to determine the phase diagram and physical properties of iron at high pressure and temperature since the 1950s. Much of our initial knowledge on the density and phase transformation of iron at high pressures is from dynamic shock wave experiments (e.g., Bancroft et al, 1956 McQueen and Marsh, 1966 Barker and Hollenbach, 1974 Brown and McQueen, 1986). However, structural information for high-pressure polymorphs of iron was obtained from static compression experiments combined with in situ X-ray diffraction measurements (e.g., Jamieson and Lawson, 1962 ...
