In situ observation of phase transition of silico-ferrite of calcium and aluminium
Silico-ferrite of calcium and aluminium (SFCA) is a bonding phase in the iron ore sinter. The phase
transition upon melting of SFCA was investigated with Differential Scanning Calorimetry and
Confocal Laser Scanning Microscope. The initial melting of SFCA occurred at 1183.2°C and a
massive melting was found at around 1351.1–1358.2°C. A phase transition-melting was investigated
at 1476.5–1478.7°C. The liquid phase was composed of immiscible phases. The present results
would be utilised to design a new iron ore sinter for better processing performance in a hydrogenenriched
ironmaking process.
