A very fine highly water absorbent clay material that imparts unique plastic and adhesive properties to bodies and suspensions. It is found in compact blocks in sedimentary rocks and looks like soil. It feels somewhat greasy smooth and the dried material is light in weight. It has low drying shrinkage and does not create precipitates when meeting electrolytes in slurries.

The high degree of refining plus the dispersant adsorbed on the product determine the self-dispersing characteristics. Engelhard, Zemex, Floridin and Active Minerals Co are producers that mine the same stratum in Florida. Product names include "Actigel", "Minugel", "Attagel" and "Gel". All these attapulgite products are chemically very consistent & mostly differ in the amount of grinding & refining.

Links provided herewith give much more information. One popular use of this material is to make cat litter.
