In this work, DDR zeolites were synthesized by sonochemical method without the application of any heat energy at room temperature. The synthesized zeolites were characterized by X ‐ray diffraction ( XRD ), infrared ( IR ) spectral analysis, and field‐emission scanning electron microscopy ( FESEM ). XRD and IR results showed that phase pure DDR zeolite was started to form at room temperature after 24 h of aging and completed the formation after 5 d of aging. The Brunauer–Emmett–Teller ( BET ) surface area of the powder was found to be 202 m 2 /g. The FESEM micrograph and elemental analysis showed that desired atomic ratio of the DDR zeolite was obtained after 5 days of synthesis.
