Thermodynamics of phosphorus in the MnO-SiO_2-Fe_tO system

摘要

Towards the resource circulating society, material's design and creation for inverse-utilization of recycle barriers have been required and feasibility study on the creation of ultra-steel containing high impurities such as phosphorus have been carried out~(1)). For proper understanding of deoxidation and solidification process for the steel containing high impurities, thermodynamic properties of the oxide systems equilibrated with high impurities are necessary. In the present study, the thermodynamic property of phosphorus in the MnO-SiO_2-Fe_tO system has been investigated by measuring the phosphorus partition between the slag and solid or molten iron.
