In this outline, the stability of solid/liquid dispersion was theoretically investigated the matter from all angles by using the modified DLVO theory. The stability was handled various considerations such as a production and characteristics of electrical double layer, total interaction(VT) that consisting of attractive force(VA) and repulsion(VR). coagulation, the stability ratio(W), critical flocculation concentration (cfc) and zeta potential(ξ) etc. It was possible for us to examine with the stability ratio(W), critical flocculation concentration (cfc) and zeta potential(ξ) that may estimation of stability of solid/liquid dispersion experimentally.
