摘要：

Calcium ferrite slags, used in continuous copper-converting processes.. can be described by the "Cu2O"-FeO-Fe2O3-CaO system at copper metal saturation. Equilibration/quenching/electron probe X-ray microanalysis (EPMA) techniques with primary phase Substrate support have been used to experimentally determine liquidus and solidus data for this system for the primary phase fields of cuprite, dicalcium ferrite, and spinel from 1100 degrees C to 1250 degrees C. The resulting measurements are presented as liquidus and solidus isotherms in the "Cu2O"-"Fe2O3"-CaO system in equilibrium with metallic copper.
