On the nature of the melting line of bcc sodium

الأصل · EN

Recent experiments have obtained the melting line of sodium up to pressures of about 130 GPa, finding that the melting line from the bcc phase reaches a maximum at a temperature of c.a. 1000 K and a pressure of 31 GPa, and at higher pressures the fusion temperature decreases continuously up to 118 GPa. Here we report results of a study based on first principles molecular dynamics, clarifying the nature of the maximum and subsequent decreasing behavior found in the melting line of sodium.
