ABSTRACT:
A porous substrate with a seed crystal-containing layer for manufacturing a zeolite membrane includes: a ceramic porous substrate, and a seed crystal-containing layer containing a zeolite powder to function as a seed crystal for forming a zeolite membrane and a ceramic powder and being loaded on a surface of the ceramic porous substrate and fired to fix the seed crystal-containing layer on the porous substrate. The porous substrate with a seed crystal-containing layer used for manufacturing a zeolite membrane inhibits a defect such as a crack from being generated in the zeolite layer upon manufacture or use by manufacturing a zeolite membrane by the use of the substrate which then can be subjected to air-spraying, washing, and processing for the purpose of removing a foreign substance, etc., prior to hydrothermal synthesis.
