The effect of MgO on phase development in a hematite-ilmenite ore sinter was investigated employing a vertical tube furnace by raising the temperature at 30 K/min to 1553 K. The phases developed after sintering were identified in terms of XRD and EDS analyses. The distribution of metallic elements after sintering were figured out through EPMA mappings. The results showed that the formation of MgO·Fe2O3(s) and Mg-rich SFCA increased in the sinter blend, and that more Ti was retained in the Fe-rich phase with increasing MgO. It is believed that the formation of CaO·TiO2·SiO2 phase decreased with increasing the addition of MgO.
