The flocculation values of Cs- and Mg-montmorillonites were estimated by the relative turbidities of their suspensions in the various concentrations of CsCl and MgCl_2 solutions at pH 8.0 after each standing for one day. The outline of result is as follows : The value of Cs- and Mg-montmorillonite was about 5×10^<-3> and 2.5×10^<-4> mol L^<-1>, respectively. Both the Cs- and Mg-montmorillonites should be formed the thin-platy flocs only composed of the "face-to-face" association based on a scheme by Van Olphen (1991). While the montmorillonites saturated with univalent cations were more hydrophilic than the montmorillonites with divalent cations, the Cs-montmorillonite was hydrophobic compared with the Na-montmorillonite of which hydration degree was very high.
