Sintering is a fast process and it is unlikely that equilibrium will be reached during sintering. The reaction mechanism proposed for self fluxing sinter is summarized below : At 800-1000°C Crystallisation of iron oxide — hematite Dissociation of CaCO3 Sintering of hematite with quartz and lime. At 1050-1200°C Part of hematite + Ca0 = CaO.
