Reactions Between Iron Oxides And Alumnina-Silica Refractories

Phase equilibrium data for the system FeO-Fe2O3-Al2O3-SiO2 are used to evaluate the attack of iron oxides on alumina-silica refractories under various idealized conditions which approach those occurring in practice. The extent of attack and the nature of the reactions at various levels of O2 pressure are discussed.
