Dehydration curves and differential thermal analysis curves of several different kinds of zeolites are presented here and discussed with reference to their dehydration phenomena. The zeolites include ptilolite, heulandite, epistilbite, stilbite, laumontite, chabazite, analcime, natrolite, scolecite, mesolite and thomsonite. And it was revealed that there are some types of dehydration phenomena. These types are: (1) Natrolite type showing sharp dehydration phenomena in which water of crystallization is entirely lost.…Natrolite. (2) Analcime type showing smooth dehydration phenomena.…Ptilolite, chabazite and analcime. (3) The combined type of the two above mentioned.…Heulandite, laumontite, scolecite and mesolite. (4) The type which does not belong to any of the two types.…Epistilbite, stilbite and thomsonite.
