Abstract
Delaminated trioctahedral smectite clay compositions are provided having a substantially delaminated interlayer structure with a face-to-edge and edge-to-edge association of the clay layers and an inorganic metal oxide intercalated between the clay layers. A process for preparing delaminated smectite clay compositions comprises reacting an admixture of a trioctahedral smectite clay having an average particle size up to about 500 angstroms and a polymeric cationic hydroxy metal complex in an aqueous medium and recovering the reacted clay solids.
