KAOLIN (ALUMINUM SILICATE)

Kaolinite is the principal constituent of kaolin. Its chemical structure is Al 2 Si 2 O 5 (OH) 4 (theoretically 39.8% alumina + 46.3% silica + 13.9%) but elements are not diverted from this ideal composition. Kaolinite is a hydrous aluminum silicate prepared by the chemical weathering of feldspar and decomposition of aluminium silicate rocks.
