Calculation of the LiF-CeF(sub 3)-BeF(sub 2) and LiF-PuF(sub 3)-BeF(sub 2) ternary phase diagrams.

摘要

The LiF-CeF(sub 3)-BeF(sub 2) and LiF-PuF(sub 3)-BeF(sub 2) ternary phase diagrams were calculated from optimized binary diagrams using computer programs developed by Lukas and coworkers. The approximate overall diagrams were calculated without the use of ternary interaction terms, but inclusion of ternary terms was necessary to reproduce the experimental data for solubilities of CeF(sub 3) and PuF(sub 3) which are considerably less soluble in LiF-BeF(sub 2) liquid than predicted without ternary interaction terms.
