Analytical equation of state for pure alkali metals (lithium, sodium, potassium, rubidium and cesium) in equilibrium gas phase is proposed. This equation has a simple form, generalizes the equation of state for a perfect gas and is universal for all alkali elements. It correctly reproduces the experimental data for the equilibrium gas phase over a wide range of pressures (up to ∼ 10 5 Pa) and temperatures (up to ∼ 3 • 10 3 K). On the basis of this equation of state, expressions for thermal and caloric coefficients as well as for other physical characteristics are obtained. The results of this study confirm feasibility of the principle of corresponding states in relation to the group of alkali elements.
