Clay minerals have a sheetlike structure and are composed of mainly tetrahedrally arranged silie and octahedrally arranged aluminate groups. Kaolinite is the principal mineral in kaolin clays. It is a 1:1 clay mineral – the basic unit is composed of a 2dimensional (2D) layer of silie groups tightly bonded to a 2D layer of aluminate groups. Throughout the mineral, there is a ...
