Clays consist of fine particles (clay minerals) which under certain conditions can be dispersed in water, forming a fairly stable dispersion. The stability of the clay mineral dispersions depends on the pH, solid/liquid ratio, and most of all on the type and concentration of dissolved ions.,CSIRO PUBLISHING | Soil Research ,Critical Coagulation Concentration of Paddy Soil Clays in Sodium-Ferrous Iron Electrolyte Saejiew Atinut, Grunberger Olivier, Arunin Somsri, Favre Fabienne, Tessier Daniel, Boivin Pascal,Flocculation of swelling clay suspensions in relation to … ,The clays were made homoionic by saturating them with 1 M NaCl and CaCl2, respectively. The critical coagulation concentrations (CCC) were investigated with four levels of SAR (10, 20, 40 and 60) and two levels of (Ca:Mg) ratios (1:1 and 1:8).
