Bentonite ni amabuye y'agaciro atari icyuma afite montmorillonite nk'igice cy'ingenzi cy'amabuye y'agaciro. Imiterere ya montmorillonite ni imiterere ya kristu ya 2:1 igizwe na tetrahedroni ebyiri za silicon ogisijeni hamwe n'urwego rwa octahedron ya ogisijeni ya aluminiyumu. Hari cation zimwe na zimwe, nka Cu, Mg, Na, K, mu miterere y'imiterere igizwe n'uturemangingo twa kristu twa montmorillonite, kandi imikoranire hagati y'izi cation n'uturemangingo twa kristu twa montmorillonite ntabwo ihamye cyane, byoroshye guhindurwamo n'izindi cation. Ifite ubushobozi bwiza bwo guhanahana iyoni. Ibihugu by'amahanga byakoreshejwe mu mashami arenga 100 mu nzego 24 z'inganda n'ubuhinzi, hamwe n'ibicuruzwa birenga 300, bityo abantu bayita "ubutaka bw'isi yose".
Bentonite ifite urwego rwinshi nka:Ibumba rikora, Ubutaka karemano buhindura ibara, Organic bentonite, Bentonite ore, Calcium bentonite na sodium bentonite.
Bitewe n'imiterere yayo myiza y'umubiri n'imiti, bentonite ishobora gukoreshwa nk'ikintu gikuraho ibara, ikintu gifunga, ikintu gikingira ibidukikije, ikintu gihagarika ibara, ikintu gitera imbaraga, icyongera imbaraga, icyongera imbaraga, icyongera imbaraga, nibindi. Ikoreshwa cyane mu buhinzi, inganda z'urumuri, ubwiza, ubuvuzi n'ibindi.
