Abstract
Large crystals of NaX zeolite of a uniform size of 50 μm were grown by a continuous crystallization method from seed crystals (10 μm) in a mother solution having a composition 3.5Na2O:Al2O3:2.1SiO2:1000H2O. In order to grow crystals of zeolite X to an appropriate size by the continuous method, the mother solution was supplied into the starting solution with various seed contents (3~15 wt%) in an autoclave at 90ºC after 7 days, 12 days, 16 days, 19 days and 24 days.

Keywords: nucleation, seed, crystallization, large crystal, NaX zeolite
