ʻO ka Bentonite he mineral non-metallic me ka montmorillonite ma ke ʻano nui o ka mineral.ʻO ka ʻōnaehana montmorillonite he 2: 1 hale aniani i haku ʻia me ʻelua silicon oxygen tetrahedrons a me kahi papa o ka alumini oxygen octahedron.Aia kekahi mau cations, e like me Cu, Mg, Na, K, i loko o ka papa hana i hana ʻia e ka montmorillonite crystal cell, a ʻo ka pilina ma waena o kēia mau cations a me montmorillonite crystal cell he mea paʻa loa, a maʻalahi ke hoʻololi ʻia e nā cations ʻē aʻe. waiwai hoʻololi ion maikaʻi.Ua hoʻohana ʻia nā ʻāina ʻē i nā ʻoihana ʻoi aku ma mua o 100 ma 24 mau kahua o ka ʻoihana a me ka mahiʻai, me nā huahana ʻoi aku ma mua o 300, no laila ua kapa ʻia e ka poʻe "ʻāina honua".

He nui ka papa Bentonite e like me:Palolo ikaika, lepo bleaching maoli, bentonite Organic, Bentonite ore, Calcium bentonite a me ka sodium bentonite.
