| Abstract: | In this paper, the process of particle formation is studied by using SEM (scanning electron microscope). Meanwhile, a mechanism of growing inward is put forward. Using SEM, the amount of surfactant and spray temperature is obtained in order to prepare sieves with ordered structure with the aid of SEM. The XRD (x-ray diffractometer) and TEM (transmission electron microscope) patterns show that the ordered structure exists in the products. Accordingly, the SEM results are proved to be right by TEM and XRD. |
