| Abstract: | Based on the equation of state of Nandan iron meteorite and the PREM model of the eaath, it is calculated that the material density at the boundary between inner core and outer core of the earth is 12.83-13.41 g/cm3 and the temperature is 5440-5680 K; the material density at the center of the earth is 13.12-13.73 g/cm3 and the temperature is 5660-5990 K, respectively. !t is estimated that the inner core of the earth may be consisted of Fe-Ni alloys. |
