Preparation, Structure, and Characterization of SFCA-I

SFCA-ISFCA-I, which is the most ideal binder phase in ironIron ore sinteringSintering, was prepared via a solid-state reaction with analytical reagents. The crystal structureStructure, cold strength, and reduction behavior were individually characterized. The results indicate that SFCA-ISFCA-I crystallizes with latticeLattices parameters of a = 10.62 Å, b = 13.38 Å, c = 11.79 Å, and V = 1122.18 Å3 and SFCA-ISFCA-I has good mechanical strength. The non-isothermal reduction results reveal that the SFCA-ISFCA-I reduction is basically completed when the temperatureTemperature reaches 962 °C. The results of isothermal reduction test show that the reduction degree of SFCA-ISFCA-I is 97% when it was reduced at 900 °C for 90 min. The order of reduction performanceReduction performance is Fe2O3 > Fe3O4 > SFCA-I > CaO · 2Fe2O3 > CaO · Fe2O3 > 2CaO · Fe2O3 > Ca3Fe2Si1.58Ti1.42O12. In addition, the high-temperatureHigh temperature heat capacity of SFCA-ISFCA-I was measured and its function with temperatureTemperature was modeled.
