セルモデルによるカルシウム-カルシウムハライド系フラックスの熱力学的性質の評価

抄録

The cell model is a kind of statistical thermodynamic model for the representation of a multi component ionic liquid. This model was applied to the CaO-Ca-CaX₂(X: F, Cl) system to estimate the ternary phase diagram and thermodynamic properties. The energy parameters were determined by using the binary Ca-CaX₂, CaX₂-CaO and Ca-CaO phase diagrams and applied to the ternary phase diagram for the CaO-Ca-CaX₂ system. Activity of calcium in the CaO-Ca-CaX₂ at 1473 K was calculated and compared with the observed data. The applicability of the cell model was discussed.
