Abstract
The invention relates to the use of materials of mixed iron-manganese oxide type for high-temperature oxygen production, notably by separation of oxygen from air, and said materials can be reversibly reduced at high temperature when subjected to an oxygen partial pressure decrease and oxidized when the oxygen partial pressure is higher. The oxidized form of mixed iron-manganese oxides has a bixbyite and/or hematite structure.
