Abstract
There is disclosed a method of treating phyllosilicate materials by exposing the materials to a source of hydrogen ions to hydrate hydroxyl ions on and in the phyllosilicate structure. The source of hydrogen ions may be a simple organic, or mineral, acid, preferably formic or hydrochloric acid. The hydrated phyllosilicate may then be dehydrated and delaminated by thermal treatment.
