Bentonite ndi mchere wosakhala wachitsulo womwe montmorillonite ndiye gawo lalikulu la mchere. Kapangidwe ka montmorillonite ndi kapangidwe ka kristalo ka 2:1 kopangidwa ndi ma tetrahedroni awiri a silicon oxygen ndi wosanjikiza wa octahedron ya aluminiyamu oxygen. Pali ma cations ena, monga Cu, Mg, Na, K, omwe ali mu kapangidwe ka magawo opangidwa ndi maselo a kristalo a montmorillonite, ndipo kuyanjana pakati pa ma cations awa ndi maselo a kristalo a montmorillonite ndi kosakhazikika kwambiri, komwe ndikosavuta kusinthana ndi ma cations ena. Ili ndi katundu wabwino wosinthana ma ion. Mayiko akunja agwiritsidwa ntchito m'madipatimenti opitilira 100 m'magawo 24 opanga mafakitale ndi ulimi, okhala ndi zinthu zoposa 300, kotero anthu amatcha "nthaka yapadziko lonse".
Bentonite ili ndi mitundu yosiyanasiyana monga:Dongo logwira ntchito, Dothi loyeretsa lachilengedwe, Organic bentonite, Bentonite ore, Calcium bentonite ndi sodium bentonite.
Chifukwa cha mphamvu zake zabwino zakuthupi ndi zamakemikolo, bentonite ingagwiritsidwe ntchito ngati decolorizer, binder, thixotropic agent, suspending agent, stabilizer, filler, feed, catalyst, ndi zina zotero. imagwiritsidwa ntchito kwambiri mu ulimi, makampani opanga zinthu zopepuka, zodzoladzola, mankhwala ndi zina.
