Abstract: The present invention provides a method for manufacturing zeolite which is useful as catalyst carrier for exhaust gas clean up by decomposition, reduction or oxidation catalyst carrier for synthesis and/or decomposition of organic or inorganic chemicals, and membrane for selective separation of organic substances, gases and inorganic cations. This new method is one in which a crystalline silica or amorphous glass contained in a fired ceramic substrate is used as a silica source for forming a natural or synthetic zeolite film on the ceramic substrate, while at the same time making the ceramic substrate porous.
