Abstract:
1. A process for producing oxygen at high temperature with an oxygen separation material comprising at least one compound responding to the formula A x BO 2-δ yH 2 O having a lamellar structure composed of sheets generated by the sequence of octahedra connected to one another by the edges, whereby A is at least one of the elements IA or IIA of the periodic classification of element, B is at one of the elements IIIB to IIB of the periodic classification of the elements, wherein B includes Mn, 0<x≦2, 0≦y≦2, and −0.4≦δ≦0.4, wherein: the partial pressure of oxygen on the material is diminished or the temperature to which the material is subjected is augmented so it releases a portion of its network oxygen in the form of gas O 2 ; then said material is subjected to a higher partial pressure of oxygen or this temperature is diminished so it re-oxidizes.
