Nanosized NaY zeolite with crystal size below 100 nm was synthesized by microwave heating method under reflux. Crystallization rate for adding citric acid is close to that of adding rare earth ions (Ln(3+)), and furthermore, synthetic NaY zeolites both possess close crystal size about 40 nm and SiO2/Al2O3 ratio(5.2), with which is smaller insize and higher in ratio than that of no adding synthesis under the same condition. Compared to crystal size of NaY zeohte synthesized by conventional heating with the same composition, crystal size synthesized by microwave heating is reduced and that crystallization time is shortened remarkably, which fully testify that the microwave heating possesses rapid and uniform as well as reducing crystal size characters.
