Bentonite with montmorillonite as the main mineral composition of nonmetallic minerals, montmorillonite structure is made up of two silicon oxygen tetrahedron clip a layer of alumina 2:1 type of octahedral crystal structure, because of montmorillonite crystal cell layer structure formed by some cation, such as Cu, Mg, Na, K, etc., and the cation with montmorillonite crystal cell function is not very stable, easy to by other cation exchange, therefore has good ion exchange.

Bentonite powder can be used to make bentonite cat litter
And it's Characteristics for bentonite cat litter:
The product is spherical, irregular particles, insoluble in any solvent, non-toxic. It has strong water absorption, adsorption and adhesion.
