The condition of the adsorbed water, the interlayer water and the constitution water of clay minerals are introduced in outline in the review. The volume and the dehydration temperature of the interlayer water vary by a kind of the exchangeable cation. Also the interlayer water is put in good order and the condition is different from the ordinary liquid water. The interlayer distance shrinks at about-40°C and the interlayer water in this state looks like the same H2O as one of the orderly arrangement under high pressure.The clay minerals rehydrate immidiately after the constitution water is dehydrated at 550°C-750°C. The dehydration temperature of the rehydrated water is about 550°C and lowered than the primary dehydration temperature. The rehydrated water is different from the original OH and appears as zeolitic water which is catched in the hole of dehydrated OH. But the constitution water is restored as lattice OH by a strong hydrothermal treatment. The constitution water is broken with the destruction of the octahedral layer by acid treatment and also by strong consecutive grinding. These facts are comfirmed by analyses of DTA, X-ray analysis and IR etc.
