    • Disclosed is a method for producing a DDR zeolite, which can be carried out using materials that are less harmful to the environment. The method for producing a DDR zeolite has a short hydrothermal synthesis time and does not require continuous agitation of the raw material solution. Specifically disclosed is a method for producing a DDR zeolite, which comprises: a raw material solution preparation step in which a raw material solution that contains 1-adamantaneamine, silica (SiO2) and water at a molar ratio 1-adamantaneamine/SiO2 of 0.002-0.5 and a molar ratio water/SiO2 of 10-500 but does not contain ethylenediamine is prepared; and a crystal growth step in which hydrothermal synthesis is carried out while having the raw material solution and a DDR zeolite powder in contact with each other, so that crystals of DDR zeolite are grown using the DDR zeolite powder as a seed crystal.

    • A process for production of a DDR-type zeolite membrane, which comprises: both a seed crystal-forming step of immersing a porous substrate in a seed crystal-forming raw material solution which contains a DDR-type zeolite powder dispersed therein and performing hydrothermal synthesis to form plural DDR-type zeolite crystal particles on surface of the porous substrate, and a membrane-forming step of immersing the resulting porous substrate with DDR-type zeolite crystal particles on the surface in a membrane-forming raw material solution which is free from DDR-type zeolite powder and performing hydrothermal synthesis to form a DDR-type zeolite membrane on the surface of the porous substrate. According to the process, a dense DDR-type zeolite membrane can be formed, and the vessel used in the synthesis can be prevented from being damaged.
