摘要: We made an attempt to predict location of the melting line polymeric nitrogen using two equations for Helmholtz free energy: proposed earlier cubic gauche-structure and developed recently liquid polymerized nitrogen. The P–T relation, orthobaric densities latent heat were determined a standard double tangent construction. estimated temperature decreases with increasing pressure, alike molecular–nonmolecular transition in solid. discuss possibility triple point (solid–molecular fluid–polymeric fluid) at ∼80 GPa observed maximum
