    Abstract: A method for synthesizing a crystalline Kenyaite-type silicate comprises preparing a mixture comprising sources of alkali metal cations (AM), silica, a non-alkali metal (M) of valence n, water and an organic compound (R), selected from an alkylamine, a trialkylamine, a tetraalkylammonium compound and trimethylhexamethylene diamine, said alkyl having 1 to 12 carbon atoms, and said mixture having a composition, in terms of mole ratios, within the following ranges: SiO2/MmOn at least about 40, H2O/SiO2 5 to 200, OH /SiO2 0 to 5, AM/SiO2 0.05 to 3, R/SiO2 0.01 to 3. The mixture is maintained under sufficient conditions to form crystals of the required silicate and the silicate crystals are then recovered. The invention further includes a method for pillaring the resulting layered silicate.
