Porosity, Mineralogy, Strength, and Reducibility of Sinter Analogues from the Fe2O3 (Fe3O4)-CaO-SiO2 (FCS) Ternary System

The presence of Ca-ferrite and silico-ferrite-of-calcium-and-aluminium (SFCA) bonding phases is thought to be crucial to maintain sinter quality due to their high reducibility and strength levels. However, new evidence suggests that porosity might be an equally important factor controlling reducibility, in addition to mineralogy. This work aims to fundamentally understand the development of porosity in simple sinter analogues from the …
