Get PriceMay 17, 2021The CaO3(Al,Fe)2O3, (C(A,F)3), phase forms a solid solution in the FeO-Fe2O3-CaO-Al2O3 system and is an end member of the SFCA (Silico-Ferrite of Calcium and Aluminum) suite of solid solutions observed in industrial iron ore sinters. SFCA acts as a bonding phase in these sinter materials so an accurate description of the phase equilibria and thermodynamic properties of this phase can be
Get PriceSilico-ferrite of calcium and aluminum (SFCA) is the major bonding phase in iron ore sintering process and is critical to enhancing the sinter properties, such as reducibility and mechanical strength in subsequent blast furnace operations. The phase relations foundations of the alumina-free silico-ferrite of calcium (SFC) have been previously experimentally investigated in air by the authors
Get PriceThe iron itself is usually found in the form of magnetite (Fe3O4), hematite (Fe2O3), goethite (FeO(OH)), limonite (FeO(OH).n(H2O)) or siderite (FeCO3). Ores carrying very high quantities of hematite or magnetite (greater than ~60% iron) are known as natural ore or direct shipping ore, meaning they can be fed directly into iron-making blast
Get PriceHematite is the mineral form of iron (III) oxide (Fe2O3), one of several iron oxides. The name hematite is derived from the Greek word for blood αἷμα haima because hematite can be red, as in rouge, a powdered form of hematite. The color of hematite lends itself to use as a pigment. Hematite is an antiferromagnetic or weakly ferromagnetic.
