Calculation of the thermodynamic properties of liquid Na-K-Cs alloy by pseudopotential method

The pseudopotential method is used to calculate the potentials of pairwise interactions and excessive thermodynamic properties of ternary metallic melts of Na-K-Cs system. It is ascertained that alloy formation process is a primary factor affecting Na-Na pairwise interaction. In the transition from pure components to ternary alloy the coordinate of the first pair potential minimum does not practically shifts, and the depth of the potential well increases. Temperature variations do not affect the nature of the pairwise interaction but results in a deeper pair potential minimum
