The structure evolution of kaolinite flocs during their formation in aqueous medium was studied under a scanning electron microscope by hypercritical drying with liquid CO2, as a function of Fe electrolyte content. Without any Fe electrolyte, a sediment with uniform porosity formed by accumulation of particles under gravity. Fresh Fe electrolytes made it possible to aggregate the kaolinite particles to flocs with an architecture consistent with diffusion limited aggregation (DLA). With 0.67 mM… CONTINUE READING
