Abstract

This paper critically reviews published research on silico-ferrite of calcium and aluminum (‘SFCA’) phases, the major bonding phases found in modern iron ore sinters. In particular, we focus on describing the different ‘SFCA’1 phases formed in iron ore sinter and examining their phase chemistry, crystal structures, characteristic textures and microstructures, and formation conditions. Information for the two main bonding phases SFCA and SFCA-I are reviewed and, based on a critical analysis of the data, we suggest future research directions required to generate the information necessary to fully describe the properties of both phases.

1Throughout this text the acronym ‘SFCA’ in single quotation marks refers to undifferentiated ‘SFCA’-like phases. These may consist of substituted calcium ferrites, SFCA sensu stricto and SFCA-I.
