Theory of the iron equation of state and melting curve to very high pressures
Technical Report
·
OSTI ID:5946600
A semiempirical equation of state for iron has been constructed by dividing the total energy into mean field, interatomic pair potential, and electronic thermal terms. The five adjustable parameters are fitted to the experimental isotherm, Hugoniot, and melting curve. Superimposing the estimated pressure and temperature conditions of the presumably pure solid iron inner core of the earth onto the calculated phase diagram shows an unexpected discrepancy.
