Hydrophilicity of aluminosilicate materials is an important characteristics as an index of the degree of hydrothermal reaction and hydration of starting materials. Heat of immersion of amorphous aluminosilicate after hydrothermal treatment have been studied to clarify the meaning of the leading time of hydrothermal reaction. The heat of immersion and specific surface area are compared with structural data, XRD, DTA-TG, and IR. The hydrothermal reaction is divided into two stages: (1) hydration of amorphous aluminosilicate for the first stage and (2) crystallization of kaolinite for the second stage. The leading time of hydrothermal reaction is attributed to the hydration period of starting material.
