This paper presents a review of different chemical compositions that are used in the production of mixed ionic-electronic conducting membranes with the perovskite structure. In these dense membranes, oxygen from the air is permeated through ionic and electronic processes, and high oxygen permeation fluxes are observed at high temperatures (800-900 ºC). Various membranes were compared for their performance and properties after being synthesized by different methods
