Overview
Bentonite is a natural montmorillonite clay. Sodium bentonite swells strongly in water and forms a stable gel, which makes it the standard for drilling fluids, diaphragm walls, piling and foundry sand. Calcium bentonite swells less but adsorbs well, so it is used for clarification, as a pellet binder and as a carrier for agrochemicals.
