    core

## Description

- description: Ni is the second most abundant element in the Earth’s core. The melting
    temperature of Ni is shown to be 700 to 800 K higher than that of Fe at 323 to
    360 GPa. hcp, bcc, and liquid phase relations differ for Fe and Ni. Ni can be
    a bcc stabilizer for Fe at high temperatures and inner core pressures. A small
    amount of Ni can accelerate Fe’s crystallization at core pressures. These results
    suggest that Ni may substantially impact the structure and formation process of
    the solid inner core.
