Evaluation of Thermophysical Properties of Sodium as Surfaces of the Temperature and the Density

Temperature- and density-dependent functions were constructed for the pressure, heat capacity, and thermal conductivity of sodium. In evaluating these functions, the latest available sodium data were used. The near critical part of the properties was modeled with the method of the critical exponents. Each function is defined for all temperatures above the melting point and for all densities below the density of the liquid.
