Abstract
In this paper, published studies on the bonding phase of calcium ferrite are reviewed. As the main bonding phase of high-basicity sinter, calcium ferrite has the advantages of high strength, good reducibility and easy formation of liquid phase. In particular, we emphasize the formation process of calcium ferrite phases, especially Silico-Ferrite of Calcium and Aluminum(‘SFCA’), and the influence of common gangue components (Al2O3, SiO2, MgO) on its formation. Based on the critical analysis of the current data, some deficiencies in this field are put forward and the research directions we think will be key in this field in the future are attached, so as to improve the theories related to calcium ferrite in iron ore sintering. The relevant results provide theoretical basis for understanding the formation process of calcium ferrite and producing high quality sinter.
