Abstract
The transport properties of an A-type zeolite membrane are traced by monito ring the diffusion paths of ethane and propane from ca. 300 nm up to 10 mu m; over distances < 1 mu m, the diffusivities are found to be comparable wi th those in a mono-crystal, while for large displacements by a factor of tw o to three smaller diffusivities were observed.
