A ‘universal’ dependence is predicted of the reduced critical parameters (temperature, density, and pressure) on the crystal anharmonicity. The model, which employs the ‘universal’ zero‐temperature equation of state in a version of fluid perturbation theory, is apparently the first to predict correctly the critical temperature and density for both the rare gases and Alkali metals.
