Synthesis of crystalline CHA Zeolite powder and highly oriented defect-free CHA Zeolite membrane is described herein by the secondary growth of small pore silicoaluminophosphate powder having chabazite (CHA) type framework crystals from economic raw material Zeolite films are formed through the gradual growth and integration of individual zeolite seed crystals within a designated seed layer and through the secondary growth method by synthesizing the membrane of the zeolites using a hydrothermal process. Thereby generating defect-free membranes with improved permeance by utilizing the smaller seed crystals typically ranging from 2 to 5 μm. Ultrasound has been used to accelerate the crystallization process by enhancing mass transfer, promoting uniform nucleation, and facilitating the dispersion of precursor materials as well as to improve productivity in terms of enhanced adherence of seed crystals to support surfaces, leading to crystal quality and morphology that leads to faster synthesis times, as evidenced by the rapid generation of seed crystals.
