Abstract

In this work, the main characteristics of the crystal–homogeneous phase transition in argon are calculated on the basis of the correlation cell-cluster expansion. Along the crystallization and melting line, the heat capacity at constant pressure is calculated for the crystalline phase and for the homogeneous phase. A monotonic decrease of the heat capacity at constant pressure with increasing temperature is observed. A comparison between theoretical data and experimental results is carried out, showing good agreement.
