Crystal size of zeolite often becomes an issue owing to its functional appearance and processibility in case of utilizing it industrially. There are some theoretical approaches to the crystallization and the crystal growth of zeolite crystal, and much work has been reported on those themes. Furthermore, there have been many investigations into the dominant factor of crystal size. With industrial necessity, we have thoroughly examined the controlling the crystal size of various zeolites through many years. In this paper, we report what kind of factors are there for controlling the crystal size of zeolite and to what extent can the crystal size be changed, from the industrial point of view.
