Abstract
It is generally accepted that fayalite is formed in sinter by the reaction between partiallyreduced iron-oxide and silica. Several investigators have reported the formation of fayaliteby the reaction between ferrous oxide and silica experimentally. It is not yet established, however, whether fayalite is formed only after iron-oxide is reduced until ferrous oxide or magnetite reacts directly with silica to form fayalite during a sintering process. This. experiment intended to ascertain whether the reaction of magnetite and silica in solid state results in the formation of fayalite, and confirmed the possibility of this reaction.
