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+, Ca+, Fe3+ and Al, and present in the shape of needles, fibers or fibrous clusters. Its ideal molecular formula is:Mg5Si8O20(HO)2(OH2)4·4H2O. And the theoretical chemical component is SiO2 56.96%, (Mg, Al, Fe)O 23.83%, H2O 19.21%.
