Bentonite Powder is absorbent clay, which was given its name after the Cretaceous Benton Shale by Wilbur C. Knight, who discovered it in 1898. The clay comprises mostly montmorillonite. This acquires the name of the dominant element present in the material, such as potassium, calcium, sodium and aluminium. Thus, if the content of calcium is more it is, then, called calcium bentonite. The material is mainly used as drilling mud, foundry-sand bond in steel foundries, absorbent, purifier and groundwater barrier.
