Attapulgite clay

The attapulgite 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+, Ca2+, Fe3+ and Al3+, and present in the shape of needles, fibers or fibrous clusters. The 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, it has certain plastic and adhesive characters.
