Using a fluid cell model for description of a phase transition in simple liquid alkali metals
Abstract
This article embraces a theoretical description of the first order phase transition in liquid metals with application of a cell fluid model. The results are obtained through calculation of the grand partition function without usage of phenomenological parameters. The Morse potential is used for calculation of the equation of state and the coexistence curve. Specific results for sodium and potassium are obtained. Comparison of outcome of analytical expressions with data of computer simulations is presented.
