The initial sinter melt of a CaO–Fe 2 O 3 binary system forms at a temperature near 1200 °C during sintering. Therefore, the change in pore structure and formation of cracks while heating up the sinter mix to 1200 °C have a large influence on melt formation, due to the changes in the area available for sinter reactions. In addition, decrepitation of iron ore particles affects the physical
