Title
(EN) RARE-EARTH MANGANESE OXIDES FOR GAS SEPARATION AND OXYGEN STORAGE
(FR) OXYDES DE MANGANÈSE ET DE LANTHANIDE POUR LA SÉPARATION DES GAZ ET LE STOCKAGE DE L'OXYGÈNE
Abstract
(EN)
A manganese oxide contains M1, optionally M2, Mn and O. M1 is selected from the group consisting of In, Sc, Y, Dy, Ho, Er, Tm, Yb and Lu. M2 is different from M1, and M2 is selected from the group consisting of Bi, In, Sc, Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb and Lu. These ceramic materials are hexagonal in structure, and provide superior materials for gas separation and oxygen storage.

L'invention concerne un oxyde de manganèse contenant M1, éventuellement M2, Mn et O. M1 est choisi dans le groupe comprenant In, Sc, Y, Dy, Ho, Er, Tm, Yb et Lu. M2 est différent de M1, et M2 est choisi dans le groupe comprenant Bi, In, Sc, Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb et Lu. Ces matériaux céramiques ont une structure hexagonale et constituent d'excellents matériaux pour la séparation des gaz et le stockage de l'oxygène.
