The hydration rate of allophane and imogolite has been estimated by means of an adiabatic vapor absorption calorimeter. The hydration amount of allophane and imogolite were 16.6 and 19.4%, respectively, at dehydrated temperature of 100℃. The maximum hydration rate of allophane and imogolite were 0.063 mmol/g・s and 0.087 mmol/g・s, respectively, at same dehydration temperature. When allophane and imogolite were dehydrated at temperatures below 100℃, the hydration rate of allophane was larger than that of Mg-A type zeolite, and the hydration amount of allophane was larger than that of B type silica gel. Both hydration rate and hydration amount of imogolite were larger than those of Mg-A type zeolite and B type silica gel. Therefore, allophane and imogolite are suitable for heat exchange absorbents of the heat pump and speedy drying desiccant.
