| 英文摘要 | growth of mcm-22 zeolite films on glass substrates was studied with the focus on the understanding of the unusual vertical crystal orientation. the films formed were characterized by scanning electron microscopy and x-ray diffraction. separate thin disk-like mcm-22 crystals were found vertically oriented at the early crystallization stage. with crystallization the crystals grew into thick disks and finally into continuous films. the vertically oriented mcm-22 thin crystals could be developed from the orientation of columnar mcm-22 nuclei, which have larger parameters in their c-directions than those in a and b directions. the preferred orientation of mcm-22 nuclei and the fast growth rate in the layer direction are responsible for the vertical growth of mcm-22 zeolite films.
