Properties Bentonite

At high enough concentrations, these suspensions begin to take on the characteristics of a gel. Suspensions are formed when water molecules penetrate into platelet interlayers. Here, hydrogen bridge bonds are formed by the hydrogen atoms contained in the water molecules. Platelets become isolated from each other, while bonded through interposition water. When left still, a mesh is formed which
