Development of Coordination-Cluster Model for Analysis of Interactions in Melts of Li-Cr-N System

摘要

Theoretical correlations based on the coordination cluster model are used to obtain the solubility of chromium in liquid lithium as a function of nitrogen content. It is shown that the derived equations are useful to provide understanding of a relationship between thermodynamic properties and local ordering in the Li-Cr-N melt. When nitrogen is present, the temperature dependence of the solubility of chromium differs significantly from a linear dependence and this can be understood in terms of the thermochemistry of Li-Cr-N ternary system. Calculated values of the chromium solubility in liquid lithium as a function of absolute temperature agree in essence with available experimental data.
