Thermodynamics of Phosphorus and Silicon Solutions in Manganese Based Melts

摘要

The study of Mn-P and Mn-Si systems is of great importance to develop and improve on dephosphorization processes in manganese based melts, production of silicomanganese, and silicothermic process to produce refined manganese ferroalloys. Published data on manganese activity in Mn-P [1-4] and Mn-Si [5-8] melts are contradictory. It results in a lack or reliable information on phosphorus and silicon activity in these melts, which is obtained through integrating the Gibbs-Dugem equation with the knowledge of manganese activity.
