A model for calculating the latent melting heat of pure metals in the process of their fusion with consideration for the phonon “Casimir force” analogue is presented. The model makes it possible to explain the difference between the experimental and theoretically calculated specific melting heats by the sum of jumps in the configurational and vibrational entropies during the solid–liquid phase transition. The described approach also provides the possibility of estimating the volume jump under melting from the crystal geometry and thermodynamic parameters of a material.
