Abstract

The method for determining the thermal expansivity of hexagonal close-packed (HCP) iron at high pressure and high temperature developed by Isaak and Anderson [Physica B 328 (2003) 345] has been used taking the input parameters derived from the seismic data and the Stacey reciprocal K-primed equation of state [F.D. Stacey, and P.M. Davis, Phys. Earth Planet. Inter. 142 (2004) 137]. Values of thermal pressure have been obtained from the formulation presented by Shanker et al. [Phys. Earth Planet. Inter. 147 (2004) 333]. Pressure (P)–volume (V)–temperature (T) relationships and thermal expansivity for HCP iron at high P and high T are obtained. The results for thermal expansivity are found to compare well with the corresponding results derived by Isaak and Anderson using the laboratory data.
