The modified Simon equation and some properties of substances on the melting line
Annotation
Two versions of modified Simon equation, which contain a correction factor with additional parameters, are suggested for describing the melting lines of elementary substances. It is demonstrated that the generalizations found for the Simon equation (the universality of component $\Delta \tilde s_1$ of entropy of melting, the convergence of the extreme position of melting line at $T \to 0$ with the limits of thermodynamic stability of coexisting crystal and liquid, and the correlation of the pole of melting line $p_*$ with internal pressure $p_i$ in the condensed phase in the vicinity of the triple point) retain stability to the variation of the form of dependence $p_{\text{melt}} = f(T)$.
