Outline
A theoretical Hugoniot curve of iron has been calculated based on Grüneisen equation of state and internal energy conservation consideration, using a set of optimized or thermophysical parameters and both ε- and liquid-iron models. This determined Hugoniot curve is well in accord with the revised Hugoniot data [J Appl Phys, 2000, 88: 5496] on the whole, and could be further divided into two parts. The first one can well describe the revised data below ~200 GPa with ε-phase model, while the second can approximately replicate the revised data above ~260 GPa with liquid-phase model. It is thus convinced that the range between ~200 GPa and ~260 GPa should be in solid/liquid mixed state, i.e, a small kink appearing on the revised Hugoniot at ~200 GPa is due to a solid-liquid transition, rather than a solid-solid transition at ~200 GPa that was inferred from Brown's analysis [Geophys Res Lett, 2001, 28: 4339].
