خلاصه مقاله:
In this work, nanocrystals of NaA zeolite with crystallite sizes ranging from 70-120 nm were synthesized. Nano crystalline NaA zeolites were prepared using sodium aluminosilicate solution and tetramethylammonium hydroxide organic template. The crystal species were characterized byX-ray diffraction (XRD) patterns and morphology of the zeolites subjected to crystallization was characterized by scanning electron microscopy (SEM). At this research, the zeolite crystallinity 89% was obtained. The effect of water content on crystal size was studied and the results showed that the crystal size decreases with decreasing the water content.
