Application of the thermodynamic approach to the assessment of the surface energy state of the disperse materials

Using Zismanmethod, values of the critical surface tension of liquid (ethanol solutions with different water content) on the border of the dispersed system (fractions of a sandy soil were crushed to the micro- and nanosized state) were calculated. The efficiency of using complex Hamaker constant A* and the critical surface tension c as criteria for the process of the dispersed materials surface formation and characteristics of theenergy state was shown.
