Abstract: Zeolites have been widely used in industrial processes due to their uniform and intricate channels, large surface areas, high stabilities and excellent shape-selectivity. New methodology with high efficiency, low energy-cost and easy-fabricating is of great importance for zeolite synthesis. A wet-gel crystallization method for zeolite X synthesis is proposed from improving the conventional hydrothermal route. XRD, SEM and N2 isotherms were performed to characterize the structure of products. The yield of solid products was also investigated. It showed an obvious promotion of products yield within the same reactor compared with the conventional synthesis route of zeolite X. The products exhibited similar physical and chemical properties with that of conventional zeolite X and also good performance in the calcium ion exchange processes.
