Specific properties originated from zeolite structure are unique, which accerelates reserch activity toward finding of new physical phenomena and development of new devices. In order to carry out these experiments, millimeter to centimeter-sized zeolite single crystals are essential. The size of synthehtic zeolites is, however, ranged up to a few hundreds micrometers.

In this review, the reason of the limited size is discussed when zeolites are synthesized as meta-stable phase. Followed by this consideration, examples are introduced to grow millimeter to centimeter sized cancrinite and sodalite as stable phase by hydrothermal and flux growth methods.
