Fabrication of the c-axis oriented zeolite L compacts using strong magnetic field

Abstract: Preferentially oriented thick and thin compacts of zeolite L with a large anisotropy in their crystal structures were successfully prepared by colloidal processes in a strong 12T magnetic field. The orientation along the direction of the applied magnetic field was characterized by XRD using slip-cast compacts. In the present experiments, it was revealed that the c-axis of zeolite L was an easy-magnetization axis. The c-axis oriented zeolite L layer with a thickness of ca. 3μm was formed on a porous ceramics substrate via electrophoretic deposition in a strong magnetic field applied perpendicular to the surface of the substrate.
