I-Bentonite iyiminerali engeyiyo i-metallic kunye ne-montmorillonite njengeyona nto iphambili yamaminerali.Isakhiwo se-montmorillonite yi-2: 1 i-crystal structure eyenziwe ngee-silicon oxygen tetrahedron ezimbini kunye noluhlu lwe-aluminium octahedron ye-oxygen.Kukho ezinye cations, ezifana Cu, Mg, Na, K, kwisakhiwo umaleko eyenziwe montmorillonite crystal iiseli, kunye nentsebenziswano phakathi kwezi cations kunye neeseli crystal montmorillonite azinzanga kakhulu, nto leyo kulula ukutshintshiselwa ngamanye cations. ipropathi yokutshintshiselana nge-ion elungileyo.Amazwe angaphandle asetyenziswe kumasebe angaphezu kwe-100 kwiinkalo ze-24 zemveliso yezoshishino kunye nezolimo, kunye neemveliso ezingaphezu kwe-300, ngoko abantu babiza ngokuthi "umhlaba jikelele".

I-Bentonite inamabakala amaninzi afana nala:Udongwe olusebenzayo, umhlaba owenziwe mhlophe ngokwendalo, i-Organic bentonite, i-bentonite ore, iCalcium bentonite kunye nesodium bentonite.
