Correlation function of concentration fluctuations as a criterion of internal consistency of thermophysical properties binary metal liquids at high temperatures

The efficiency of applying the correlation function of concentration fluctuations for estimating the reliability of experimental data on Gibbs energy of solution formation, ΔG, and methods of their approximation as well as the reliability of theoretical models which reproduce the behaviour of AG, and internal consistency of the data in construction of a self-contained thermodynamic description of liquid metal solutions are discussed. The binary alkali metal systems were used as a model for checking internal consistency of the obtained experimental data from 400K up to 1200K in the entire range of concentrations.
