Ivhu ivhu rinonamira rine zvidimbu zvidiki zvejecha, uye ine ipurasitiki yakanaka chete kana mvura isingakwanise kupfuura nemo nyore.
Ivhu rakajairika rinoumbwa nemamiriro ekunze emamineti esilicate pamusoro penyika. Kazhinji, yakaneta mune situ. Izvo zvidimbu zvakakura uye kuumbwa kuri padyo nedombo rekutanga, iro rinodaidzwa kuti dongo rekutanga kana dongo rekutanga. Midziyo mikuru yerudzi rwevhu iyi ndeyesilika nealumumina, iyo chena neruvara uye inoratidzira, uye ndizvo zvinhu zvakakosha zvekugadzirira ivhu revhu.
Ivhu rinowanzo kuumbwa nemamiriro ekunze ealuminosilicate maminera epasi pevhu. Asi imwe diagenesis inogona zvakare kugadzira ivhu. Kuonekwa kwevhu panguva iyi maitiro kunogona kushandiswa sechiratidziro chekufambira mberi kwe diagenesis.
Clay yakakosha zvicherwa mbishi. Iyo inoumbwa nemhando dzakasiyana dzehydrate silicates uye imwe huwandu hwealumumina, alkali simbi oxides uye alkaline pasi simbi oxides, uye ine zvakasviba senge quartz, feldspar, mica, sulfate, sulfide, uye carbonate.
Clay zvicherwa zvidiki, kazhinji mukati meiyo colloidal saizi renji, mu crystalline kana isiri-crystalline fomu, mazhinji acho akafanana neakaumbika, uye mashoma ari akafanana tubular kana tsvimbo.
Clay zvicherwa ipurasitiki mushure mekunyoroveswa nemvura, inogona kuremara pasi pekumanikidza kwakadzika uye inogona kuramba isina kugadzikana kwenguva yakareba, uye iine yakakura nzvimbo yepamusoro. Iwo ma particles akapomerwa zvisirizvo, saka iwo ane akanaka epanyama adsorption uye epamusoro makemikari zviitiko, uye zvinoenderana nezvimwe cations. Kugona kuchinjanisa.
Zvinoenderana nehunhu uye mashandisiro acho, inogona kukamurwa kuva yevhu ceramic, ivhu rinodzora, ivhu rezvidhina uye ivhu resamende. Ivhu rakaoma rinowanzo kuve muchimiro chemabhuroko kana matombo. Kazhinji haina kunyudzwa mumvura uye ine yakanyanya kugadziriswa. Iyo ndiyo hombe mbichana zvinhu zvezvinhu zvinogadziriswa. Ivhu rakaomarara muvhu rinodzora rinoshandiswa kugadzira kuputika kwevira remoto, kudhirowa zvidhinha uye zvidhinha zvepombi yekunyungudisira huni, zvinopisa zvitofu, uye madhiramu esimbi. Mune indasitiri ye ceramic, ivhu rakaoma uye semi-yakaoma ivhu rinogona kushandiswa senge mbishi zvigadzirwa zvekugadzira kwezuva nezuva-shandisa maceramiki, ekuvaka maceramiki uye maindasitiri maceramics.
