Dissolution Equilibrium of Bismuth Vapor in Liquid Iron and the Interaction Effect of Third Element
-
摘要: 用密封反應室氣液平衡法,測定了Bi蒸氣在Fe液中的溶解平衡及第三組元Cr,Cu,C,Al和Si對Bi溶解量的影響,得到Fe液中Bi蒸氣溶解反應標準溶解吉布氏自由能與溫度的關系式,以及1873K溫度下Fe液中第三組元與Bi的活度相互作用系數.Abstract: The dissolution equilibrium of Bi vapor in liquid iron and the interaction effect of third element were conducted in a sealed Mo reaction chamber by vapor pressure method. The relationship between the standard solution Gibbs free energy of Bi in liquid iron and temperature obtained can be expressed.The interaction coefficients of third elements on Bismuth in liqind iron at 1 873 K can be deduced.
