The present study is focused in the rheological and microstructural characterization of aqueous sepiolite gels and the influence of the addition of ionic surfactants. Stable sepiolite gels were prepared using a high-shear homogenization process. The rheological characterization of sepiolite gels reveals shear thinning behaviour. It was observed that yield stress was very influenced by the addition of ionic surfactant. Cryo-SEM micrographs of sepiolite gels are in good agreement with the rheological behaviour. It has been shown that is feasible to obtain sepiolite gels with tailored rheological properties as function of the type and amount of surfactant added.

Keywords:Sepiolite;Yield stress;Ionic surfactants;Microstructure;Cryo-SEM
