Abstract : The structural properties of water adsorbed on hydrophilic intercrystalline clay mineral surfaces have been investigated by way of NMR and dielectric measuring techniques. It is shown that structural ordering of the adsorbed water layers occurs, that the adsorption takes place independent at the exchangeable cations present in the intercrystalline spaces and that these ions only modify the structural and relaxation properties of the water. The conventional hypotheses regarding the origin of the hydrophilic clay properties are shown to be untenable. (Author)
