Abstract

original image

The two-component model of coffin-shaped intergrown crystals of zeolite ZSM-5 has been verified by a combination of electron backscattering diffraction and focused ion beam milling (see picture), which respectively revealed the orientation of the channel system in the individual subunits of the crystal and allowed these building blocks to be visualized.
