AbstractLithium–lead alloys are of main interest in the liquid state. They were subjects of numerous studies, in particular, of those dealing with structural ordering in the liquid phase. Lithium–lead alloys show promise for use in liquid metal energy conversion systems and in nuclear power engineering. The results of studying thermodynamic properties of liquid Li–Pb alloys by various methods in the period from 1973 to 2018 are summarized and analyzed in the paper. Treatment of the whole set of the experimental data allowed choice of the recommended values of the thermodynamic functions for the composition interval that is of interest for technological purposes (0 ≤ xLi ≤ 0.50, with a step of 0.05). The calculation results are presented in the tabular form and are described by polynomials.
