Abstract

A seed crystal is a crystal of zeolite that is to be deposited on a support when producing a zeolite membrane complex that includes the support and a zeolite membrane formed on the support. A volume-cumulative particle size distribution of the seed crystal, measured by a laser diffraction scattering method, has a coefficient of variation of 0.5 or less and a kurtosis of 5 or less. Use of these seed crystals improves the bonding of zeolite crystals when producing the zeolite membrane. As a result, a dense zeolite membrane can be formed.
