Calculation of Activities from Phase Diagrams Involving Intermediate Compounds
-
摘要: 本文提出了一種由化合物體系的二元相圖提取組元活度數據的新方法。在該方法中,組元的活度系數是組成的函數。用該式計算Mg-sn體系的活度表明,它與實驗值符合較好。Abstract: A new method for calculating activities and activity coefficients of components from phase diagram at a fixed temperature is introduced. Analytical expressions for the calculation of activities are presented, in which activities of components are functions of the composition. The application of the expressions to Mg-Sn system shows that this method is efficient.
