Ceramic membrane; Mixed conducting oxides; Oxygen permeation; Nonstoichiometric perovskite; Tungsten substituted SCF
Nonstoichiometric oxides with mixed oxygen-electron conductivity (MIEC) attract increasing attention because of the possibility to use them as the materials for solid oxide fuel cell, as well as in catalytic membrane reactors for carrying out different petrochemical processes.
