Ivhu rakagadziriswa ivhu rinonyungudutsa rakagadzirwa nevhu (kunyanya bentonite) sezvinhu zvisina kugadzirwa, rinorapwa ne inorganic acidification, munyu kana dzimwe nzira, rozosukurudzwa roomeswa nemvura. Rine chitarisiko cheupfu huchena hwakaita semukaka, harinhuwi, harina chepfu, uye rine simba guru rekunyungudutsa. Rinogona kunyungudutsa zvinhu zvine mavara uye zve organic. Zviri nyore kunyungudutsa hunyoro mumhepo, uye kuriisa kwenguva yakareba kunoderedza simba rekunyungudutsa. Pakushandisa, zvinokurudzirwa kupisa (zviri nani pa 80-100 degrees Celsius) kuti ridzoke. Zvisinei, kupisa pamusoro pe 300 degrees Celsius kunotanga kurasikirwa nemvura yakaita se crystalline, zvichikonzera shanduko dzechimiro uye zvichikanganisa kupera kwesimba. Ivhu rakagadziriswa harinyunguduke mumvura, organic solvents, uye mafuta akasiyana-siyana, rinonyunguduka zvachose mu hot caustic soda uye hydrochloric acid, rine huwandu hwe 2.3-2.5, uye kuzvimba kushoma mumvura nemafuta.

Ivhu jena rinongowanikwa muchisikigo rine hunhu hwekuchenesesa ivhu jena, jena grey rine montmorillonite, albite, uye quartz, uye imhando yebentonite.

Zvikurukuru chibereko chekuora kwematombo egomo rinoputika akaita segirazi, asingakurumidzi mushure mekunwa mvura, uye pH yekumiswa kwayo yakasiyana neye alkaline bentonite; Kushanda kwayo kwekutsvukira kwakaipa kupfuura kwevhu rakashandiswa. Mavara anowanzo sanganisira yero yakajeka, chena yegirini, grey, ruvara rwemuorivhi, brown, chena yemukaka, peach tsvuku, bhuruu, nezvimwewo. Kune mashoma machena akachena. Kuwanda kwe 2.7-2.9g/cm. Kuwanda kwacho kunowanzova kwakaderera nekuda kwekuoma kwayo. Kuumbwa kwemakemikari kwakafanana nekwevhuwo rakajairika, nezvikamu zvikuru zvemakemikari zviri aluminium oxide, silicon dioxide, mvura, uye iron shoma, magnesium, calcium, nezvimwewo. Hapana plasticity, ine adsorption yakakura. Nekuda kwehuwandu hwayo hwakawanda hwe hydrous silicic acid, ine acidic kune litmus. Mvura inowanzo pwanyika uye ine huwandu hwakawanda hwemvura. Kazhinji, kupfava kwayo kwakanyanya, simba rekubvisa ruvara rakawedzera.

Pakuita ongororo yemhando yepamusoro panguva yekuongorora, zvakakosha kuyera mashandiro ayo ekuchena, acidity, mashandiro ekusefa, kunyudzwa kwemafuta, nezvimwe zvinhu.
