Abstract
There is provided a method for synthesizing layered silicates such as magadiite and kenyaite. The source of silica used in this method is freshly precipitated from a silicate solution. For example, this silica source may be obtained by treating an aqueous solution of sodium silicate with sulfuric acid to form an amorphous silica precipitate. This silica precipitate is not dried to reduce its activity prior to use.
