Phase relations in the quaternary system of Fe₂O-CaO-SiO₂-A1₂0₃in the temperature range between 1450℃ and 1200℃ were studied. So-called calcium-ferrite was crystallized and its composition and amount were studied. 1) Calcium-ferrite was identified as a solid solution of CaO·2Fe₂03 and CaO·6A1₂O₃ with 3.5 to 6.7 wt% solubility of SiO₂ 2) With increasing the portion of A1₂0₃in the system, the amount of the crystallized calcium-ferrite was increased and the crystallization temperature was enhanced. 3) The solubility of Al₂O₃in the calcium ferrite was increased and the solubility of Fe₂O₃ was decreased with increasing the portion of Al₂O₃in the system. 4) Increasing the portion of CaO in the system landed to increase the amount of calcium-ferrite and enhance the crystallization temperature.
