Abstract:
The present invention is a method for manufacturing inorganic membranes which are capable of separating oxygen from oxygen-containing gaseous mixtures. The membranes comprise a porous composite of a thin layer of a multicomponent metallic oxide which has been deposited onto a porous support wherein the pores of the multicomponent metallic oxide layer are subsequently filled or plugged with a metallic-based species. The inorganic membranes are formed by depositing a porous multicomponent metallic oxide layer onto the porous support to form a porous composite having a network of pores capable of transporting gases. The network of pores are plugged or filled by organometallic vapor infiltration to form an inorganic membrane having essentially no through porosity.
