METHOD FOR FORMING ZEOLITE FILM

摘要

PROBLEM TO BE SOLVED: To provide a method for efficiently producing a zeolite film having no defect and a uniform thickness on a supporter having complicated shape or a supporter having a large area. SOLUTION: This method for producing the zeolite film comprises subjecting a slurry containing seed crystals to crossflow filtration by an alumina porous supporter having 1 μm average pore diameter to make the porous supporter carry a seed crystal layer having 6 μm thickness in the interior of the pore or the surface of the supporter, and growing the seed crystal in the seed crystal layer by hydrothermal synthesis to provide the objective zeolite film having 7 μm thickness.
