Sepiolite and palygorskite (also known as attapulgite) are structurally different from other clays in two ways. Firstly, the tetrahedral sheets are divided into ribbons by inversion though they are still bonded in sheet form, and secondly the octahedral sheets are continuous in two dimensions only. They are consequently fibrous, though their ...
