| Abstract: | MAPO-11 molecular sieves were synthesized by using hydrothermal methods. The effects of mole ratio of magnesium to aluminum, type of template, crystallization temperature and crystallization time on synthesis process and properties of MAPO-11 were discussed. The synthesized samples were characterized by means of the techniques of X-ray diffraction, scanning electron microscopy and thermogravimetric-differential thermal analysis (TG-DTA). The results show that the size and shape of crystal are influenced by the mole ratio of magnesium to aluminum and the type of template. The thermal stability of MAPO-11 molecular sieves is poor. |
