Implication

Experimental analysis demonstrates edge-to-face electrostatic flocculation in kaolinite suspensions, revealing fundamental mechanisms governing clay colloidal stability.

Key Points

To elucidate the electrostatic mechanism responsible for the flocculation of kaolinite clay particles in aqueous suspensions.
Examined the colloidal and rheological behavior of kaolinite suspensions across varying pH levels and electrolyte concentrations.
Analyzed the localized surface electrical properties of kaolinite crystal edges and basal faces.
Demonstrated that kaolinite crystal edges develop positive electrical charges under acidic to neutral conditions, whereas basal cleavage faces carry net negative charges.
Showed that attractive forces between oppositely charged edges and faces drive edge-to-face aggregation into a flocculated network, which disperses when edge charges are neutralized.
