Patent ID: 8372378

Claim:
A sheet silicate produced by a process comprising, (1) mixing of silicon dioxide and/or of a silicon dioxide precursor with an aqueous solution comprising at least one tetraalkylammonium compound comprising R 1 R 2 R 3 R 4 N + and at least one base, wherein R 1 and R 2 are methyl and both R 3 and R 4 are n-propyl; and (2) heating of a colloidal solution obtained according to (1) to a temperature in a range of from greater than the boiling point of the colloidal solution to 180° C. at atmospheric pressure to give a suspension comprising at least one sheet silicate, wherein a part of the sheet silicate comprising at least silicon and oxygen obtained in (2) is added as a crystallization auxiliary in (1), and wherein said sheet silicate comprises at least the following reflections: Diffraction angle 2θ/° Intensity (%) [CuK(alpha 1)] 100 8.0-8.4 11-21 11.0-11.4 13-23 13.2-13.6 5-15 18.0-18.4 7-17 18.4-18.8 19-29 19.9-20.0 wherein 100% relates to the intensity of the highest peak in an X-ray diffractogram.
