Viscosity improvement of an Argentine kaolin by ionic treatment

Galazzo, Jorge L. / Depetris, Pedro J. / Cerro, Ramon L. / Murray, Haydn H.

AbstractAlthough kaolins from the provinces of Chubut and Santa Cruz (in Argentina's Patagonia) exhibited some promising characteristics for their use as paper-coating pigments, the rheological properties of their high solids suspensions preclude their industrial utilization. Verwey-Overbeek's theory provides the information necessary to improve the flow properties of suspensions by means of ionic treatment. Saturation with a monovalent ion — such as Na⁺ — generates an energy barrier which prevents flocculation and significantly improves the viscosity of suspensions so that they compare favorably with coating clays from Georgia in the U.S.A.
