| description | The invention relates to a preparation method of a tubular asymmetric oxygen-permeable membrane, belonging to the technical field of functional ceramic materials. By selecting the pore forming agent and controlling the bisque firing temperature, the invention implements bisque firing of a porous support under the condition of undecomposed pore forming agent, effectively prevents the compact layer slurry from entering the inside of the pores of the support in the dipping process, and enables the precursor obtained by bisque firing to have higher mechanical strength. The asymmetric bifacial dipping method is utilized to successfully attach the uniform-thickness thin compact layer to the outer wall of the tubular precursor, thereby lowering the possibility of damage of the precursor due to overhigh pressure in the dipping process, and having favorable effect on preparing complex-shape great-dimension tubular compact layers. |
