Dissolution Equilibrium of Bismuth Vapor in Liquid Iron and the Interaction Effect of Third Element

摘要

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 liquid iron at 1 873 K can be deduced.
