Reactions Between Iron Oxides and Alumina‐Silica Refractories

Phase equilibrium data for the system FeO‐Fe 2 O 2 ‐Al 2 O 3 ‐SiO 2 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 O 2 pressure are discussed.
