Formation Mechanism of NaY Zeolite Synthesized from Metakaolinite

NaY zeolite was synthesized from metakaolinite by hydrothermal method. The process of crystallization was studied by TEM, NMR, IR, XRD, SEM, HRTEM. The results show that mechanism of NaY zeolite synthesized from metakaolinite is solid transformation mechanism, and the process of synthesizing NaY zeolite from metakaolinite is an in situ process of diffusing-geling-resetting.
