    In contrast, the primary iron-rich phases in slag transform into a coarser polygonal shape with lower roundness, and some of them have hollow structures. Furthermore, the area fraction of intermetallics and Fe content in the matrix decrease gradually due to the formation and growth of sludge and subsequent natural sedimentation during melt holding.
