CXXX. The melting curve at high pressures

Abstract An attempt is made to derive theoretically the Simon formula for the variation of the melting point of a solid with pressure. The model used is similar to that of Lennard Jones and Devonshire, but the interpretation of the results is different. A formula of the right type results, but a detailed examination shows that the melting temperatures are much too high, and the reasons for the discrepancy are discussed. The theory predicts the absence of a solid-fluid critical point, and this is in disagreement with recent general work of Munster.
