CaO-Al_2O_3-CaSsat.3成分系におけるGibbs-Duhemの関係と上記の反応平衡とを組み合わせることにより導出した関係式を利用し、この活量の積とスラグ組成の関係よりスラグ中のCaO及びAl_2O_3の活量を決定した。この活量の計算過程においては、スラグ系の状態図と溶鉄中のAlとSの活量系数に関する熱力学的デ-タのみが必要である。これらは比較的精度の高いデ-タといえる。これら以外には、上記の反応の平衡定数を含め、本質的に他の研究者の報告による各種の反応の自由エネルギ-や平衡定数の値を必要としないため、利用する熱力学的デ-タに含まれる誤差の影響を受けずに活量を決定することができた。","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_19_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"科学研究費補助金
