Difference Between Kaolin and Bentonite Clay

The key difference between kaolin and bentonite clay is that the kaolin clay forms as a result of weathering of aluminium silicate minerals such as feldspar whereas the bentonite clay forms from volcanic ash in the presence of water. Kaolin refers to a mineral that is rich with kaolinite. Both kaolinite and bentonite are clay types.

Bentoniitti – Wikipedia

Bentoniitti on luonnon savea, jonka oleellisimpana osana on montmorilloniittisavi. Se pystyy absorboimaan suuria mri vett ja suotuisissa oloissa laajenemaan sen seurauksena tilavuudeltaan jopa kymmenkertaiseksi. Bentoniittia esiintyy yleisesti ympri maailmaa, mutta Suomessa sit tavataan vain vhisiss mrin.
