铜锍的组成可以用Cu_2S-FeS体系来表示,因此对铜的熔炼来说,该体系中活度的测定有一定实际意义.Krivsky,Schuhmann曾测定H_2-H_2S气体和熔锍间的平衡,并应用三元系Gibbs-Duhem积分法算出Cu_2S-FeS熔体中的活度。本文目的是根据Krivsky,Schubmann测定的熔锍和金属间的平衡,应用二元系Gibbs-Duhem积分法从事同一目的之计算,并将所得结果和Krivsky,Schuhmann的计算相比较.熔锍和金属间的反应可以用下式表示:
The composition of copper matte can be expressed by Cu_2S-FeS system, so the activity of Cu_2S-FeS system is of practical significance for copper smelting.Krivsky and Schuhmann have determined the equilibrium between H_2-H_2S gas and matte The ternary Gibbs-Duhem integration method was used to calculate the activity of Cu_2S-FeS melt. The purpose of this paper is to calculate the same purpose using the Gibbs-Duhem integral method of the binary system based on the equilibrium between the matte and the metal as determined by Krivsky and Schubmann and to compare the results with the Krivsky and Schuhmann calculations The reaction can be expressed by the following formula:
