Abstract

Oriented compacts of mordenite zeolite with an orthorhombic structure were successfully fabricated in a strong magnetic field up to 12 T by a slip casting process. The magnetic orientation was achieved by removing the large agglomerated particles from the suspensions prior to the slip casting. The b-axis oriented compacts of mordenite were fabricated in a static magnetic field. On the other hand, the c-axis orientation was made in a rotating magnetic field which was artificially produced by rotating a vessel put on a turntable in a horizontally-placed magnet. The c-axis was preferentially aligned perpendicular to the plane on which the magnetic field was rotated. The controlled orientation of mordenite was based on the anisotropic magnetic properties in the orthorhombic mordenite crystals.
