摘要：

By elaborate adjustment of synthesis conditions, cubic (Pm (3) over barn) SBA-1 samples with well-defined crystal morphologies of a large number of facets have been synthesized, which are supposed to be obtained as a result of highly isotropic crystal growth under the conditions near thermodynamic equilibrium. The high-resolution transmission electron microscope image revealed regular periodicity over very large areas and this clearly indicates the crystal is a single crystal with a well-ordered mesostructure.
