Sonochemical Synthesis Of Zeolite Na-A From Metakaolinite

Ultrasonic stimulation of constituent suspension (metakaolinite/NaOH) can improve the rate of synthesizing reaction for zeolite Na-A. Zeolite Na-A can be synthesized from the suspension by sonicating treatment at comparatively shorter exposing time than conventional heating treatment. The main effect of ultrasound for the production of zeolite Na-A in the present heterogeneous solid/liquid reaction is intense stirring the solid and liquid substances to produce relatively narrow-sized zeolite Na-A particles with higher CEC value.
