用密封反应室气液平衡法，测定了Bi蒸气在Fe液中的溶解平衡及第三组元Cr，Cu，C，Al和Si对Bi溶解量的影响，得到Fe液中Bi蒸气溶解反应标准溶解吉布氏自由能与温度的关系式，以及1873K温度下Fe液中第三组元与Bi的活度相互作用系数.
The equilibrium of Bi vapor dissolved in Fe solution and the influence of Cr, Cu, C, Al and Si on the dissolved amount of Bi were measured by gas-liquid equilibrium method of sealed reaction chamber. The Bi vapor dissolved reaction standard The relationship between Gibbs free energy and temperature, and the activity coefficient of the third component of Bi in Fe solution at 1873K are also discussed.
