Contact SupplierAttapulgite is a kind of crystalloid hydrous magnesium-aluminum silicate mineral, having a special laminated chain structure in which there is a crystalline lattice displacement existed. Thus it makes the crystals contain uncertain quantities of Na+, Ca+, Fe3+ and Al, and present in the shape of needles, fibers or fibrous clusters. Attapulgite has very good colloidal properties such as: specific features in dispersion, high temperature endurance, salt and alkali resistance, and also high adsorbing and de-coloring capabilities. Furthermore, Attapulgite has certain plastic and adhesive characters. Its ideal molecular formula is: Mg5Si8O20(HO)2(OH2)4•4H2O.
