Abstract
A zeolite membrane complex includes a support and a zeolite membrane formed on the support. The zeolite membrane is of an SAT-type zeolite. Among particles on the surface of the zeolite membrane, particles that have aspect ratios higher than or equal to 1.2 and lower than or equal to 10 account for 85% or more of the area of the surface of the zeolite membrane. This improves the orientations of the particles and also reduces the interstices among the particles. As a result, the denseness of the zeolite membrane is improved. Accordingly, for example, high gas separation performance can be obtained when the zeolite membrane complex is used as a gas separation membrane.
