Development and experimental verification of a method for assessment of consistency of the thermodynamic and structural properties of binary coolants based on systems of alkali metals
Annotation
The construction of correlation function of concentration fluctuations Scc(0)=f(T,xi) is used to validate the criterion of assessment of the internal consistency of the thermodynamic and structural properties of liquid-metal alloys, as well as of the reliability of experimental data on the Gibbs energy of solution formation ΔG, methods of their approximation, and theoretical models which reproduce the behavior of ΔG. The method is verified for the Cs—Na, K—Na, and Cs—K systems of alkali metals using the data of thermodynamic experiment in determining the Gibbs energy of formation of liquid-metal solution ΔG which is the basis for construction of the function Scc(0). The data on statistical structure factor S(0) uniquely related to function Scc(0) are obtained using the results (available in the literature) of experiments in X-ray and neutron spectroscopy, including data on diffraction and small-angle inelastic scattering.
