锰铁熔体中磷和锰的热力学性质

Thermodynamic Properties of Phosphorus and Manganese in Ferromanganese Melts

通过１４００℃下Ｆｅ－Ｍｎ－Ｃ－Ｐ系中碳的溶解平衡实验，测定了该熔体中碳的溶解度，应用热力学理论计算出，，。

Experiments on dissolution equilibrium of carbon in Fe-Mn-C-P melts were carried out at 1400℃ to measure the carbon solubility in the melts. Ac cording to the experimental results,interaction coefficient and were calcu lated in accordance with the thermodynamic theory and the equations for calcula tions of phosphorus and manganese activity coefficients are also proposed
