M-type magadiites (M2Si14O29·nH2O) were prepared by exchanging Na ion of magadiite (Na2Si14O29.nH2O) with a series of alkaline metal ions M+ (M+: Li+, Na+, K+, Rb+, Cs+), and were studied from the standpoints of the sites of interlayer cations and the influences of their cations on surface hydroxyl groups. Interlayer cations in M-type magadiites were different in the state and the position, respectively. Na ion occupied a central position in interlayer spaces with water molecules. Li ion was attracted to water molecule and situated in basin which was made up by the surface oxygen atoms. The other ions existed in the naked state and also situated in the basin. In particularly, Cs ion could be fixed by fitting tightly in eight-membered ring which consisted of basal oxygen atoms of silicate layer. These effects resulted in a changing of electron distribution and, consequently, in a lowering of the degree of dissociation on surface hydroxyl groups.
