The influence of amount of alkaline, silica and organic templates on the crystallization of nano-zeolite NaX were determined by XRD, SEM, TEM. It proved that when using suitable amount of alkaline and silica with ratio of NazO/Al2O3 = 5.0 and of SiO2/Al2o3 = 4.0, nano-zeolite NaX has crystallinity of 92 percent, particles size of 30 nm (according to XRD data). The use of organic template increases the product crystallinity and decreases the particle size.
