ABSTRACT:
There is provided a method for preparing organic-swelled layered silicate by direct crystallization from an alkaline reaction mixture containing a source of silicon oxide and organic onium compound, e.g., a cetyltrimethylammonium salt. Layered silicates containing interlayer polymeric chalcogenide are prepared by contacting the organic-swelled layered silicate with a source of polymeric chalcogenide, e.g., tetraethylorthosilicate.
