Abstract

Experimental studies of the CaO–FeO–Fe2O3–SiO2 system in air from 1200°C to 1260°C have been carried out in the Fe-rich region with particular focus on the phase equilibria associated with silico-ferrite of calcium (SFC) phase. The measurements have been made possible through the use of a modified experimental technique involving high temperature equilibration and rapid quenching followed by electron probe X-ray microanalysis (EPMA). Isothermal sections for 1220°C, 1240°C, 1255°C and 1260°C are reported providing information on the limits of stability of the SFC solid solution and the liquidus in the SFC primary phase field for the first time.
