I-Bentonite iyiminerali engeyona eyensimbi ene-montmorillonite njengengxenye eyinhloko yamaminerali. Isakhiwo se-montmorillonite siyisakhiwo sekristalu sohlobo lwe-2:1 esakhiwe ngama-tetrahedrons amabili e-silicon oxygen ahlanganiswe nesendlalelo se-aluminium oxide octahedron. Ngenxa yokuthi isakhiwo esinezingqimba esakhiwe yiseli le-montmorillonite sinama-cation athile, njenge-Cu, Mg, Na, K, njll., futhi indima yala ma-cation ngeseli le-montmorillonite ayizinzile kakhulu, kulula ukushintshaniswa ngamanye ama-cation, inekhono elihle lokushintshanisa ama-ion. Kwamanye amazwe, isetshenziswe eminyangweni engaphezu kwe-100 emikhakheni engu-24 yokukhiqiza kwezimboni nezolimo, enemikhiqizo engaphezu kuka-300, yingakho abantu beyibiza ngokuthi “inhlabathi yendawo yonke”.

I-Bentonite yaziwa nangokuthi i-bentonite, i-bentonite, noma i-bentonite. I-China inomlando omude wokuthuthukisa nokusebenzisa i-bentonite, eyayisetshenziswa kuphela njengesihlanzi. Kwakukhona izimayini zemigodi evulekile endaweni yaseRenshou eSichuan emakhulwini eminyaka edlule, futhi abantu bendawo babiza i-bentonite ngokuthi i-clay powder. Isetshenziswa kabanzi kodwa inomlando weminyaka engaphezu kwekhulu kuphela. Ukutholwa kokuqala e-United States kwakusesigabeni sasendulo saseWyoming. Ubumba lwe-chartreuse lungakhula lube yi-paste ngemva kokufaka amanzi. Kamuva, abantu babiza zonke izibumba ezinalesi sici ngokuthi i-bentonite. Eqinisweni, ukwakheka okuyinhloko kwamaminerali kwe-bentonite yi-montmorillonite, enokuqukethwe okungu-85-90%. Ezinye izakhiwo ze-bentonite nazo zinqunywa yi-montmorillonite. I-Montmorillonite ingaba ngemibala ehlukahlukene, njengoluhlaza ophuzi, ophuzi omhlophe, ompunga, omhlophe, njll. Ingakha amabhlogo aminyene noma inhlabathi ekhululekile, ngomuzwa oshelelayo lapho ihlikihlwa ngeminwe. Ngemva kokwengeza amanzi, umthamo wamabhulokhi amancane uyanda izikhathi eziningana ufike ezikhathini ezingu-20-30, uvele esimweni sokulenga emanzini, futhi uvele esimweni sokunamathela lapho amanzi engekho kahle. Uhlobo lwe-montmorillonite luhlobene nokwakheka kwamakhemikhali ayo kanye nesakhiwo sangaphakathi.
