Ingxenye eyinhloko yomhlaba we-diatomaceous njengesithwali yi-SiO2. Isibonelo, ingxenye esebenzayo ye-industrial vanadium catalyst yi-V2O5, umgqugquzeli uyi-alkali metal sulfate, futhi ophethe i-diatomaceous Earth ecwengisisiwe. Ukuhlola kubonisa ukuthi i-SiO2 inomthelela wokuzinzisa ezingxenyeni ezisebenzayo, futhi iqinisa ngokunyuka kokuqukethwe kwe-K2O noma kwe-Na2O. Umsebenzi we-catalyst uhlobene nesakhiwo se-pore sokuhlakazeka kwe-carr

ier. Ngemuva kokuthi i-diatomite iphathwe nge-asidi, okuqukethwe kokungcola kwe-oxide kuyancishiswa, okuqukethwe kwe-SiO2 kuyanda, futhi indawo ethile yendawo kanye nevolumu ye-pore nayo yanda. Ngakho-ke, umphumela wokuthwala we-diatomite ocwengiwe ungcono kune-diatomite yemvelo.

Umhlaba we-Diatomaceous ngokuvamile wakhiwa izinsalela ze-silicate ngemva kokufa kolwelwe olunengqamuzana elilodwa ngokuhlangene olubizwa ngokuthi ama-diatoms, futhi ingqikithi yalo i-amorphous SiO2 equkethe amanzi. Ama-diatom angaphila emanzini ahlanzekile namanzi anosawoti. Kunezinhlobo eziningi zama-diatom. Ngokuvamile, zingahlukaniswa zibe "i-central order" diatom kanye ne-"pinnacle order" diatom. Kuhlelo ngalunye, kukhona "uhlobo" oluningi oluyinkimbinkimbi.

Ingxenye eyinhloko yomhlaba we-diatomaceous wemvelo i-SiO2, ikhwalithi ephezulu imhlophe, futhi okuqukethwe kwe-SiO2 kuvame ukudlula ama-70%. I-Monomer diatom ayinambala futhi isobala. Umbala womhlaba we-diatomaceous uncike kumaminerali obumba kanye nezinto eziphilayo. Ukwakheka kwama-diatom emithonjeni yamaminerali ehlukene kuhlukile.

I-Diatomaceous Earth iyidiphozithi yomhlaba eyi-diatomaceous eyakhiwe ngemva kokufa kwesitshalo esinengqamuzana elilodwa esibizwa ngokuthi i-diatom ngemva kwesikhathi sokunqwabelana esiyiminyaka engaba ngu-10,000 kuya kwezingu-20,000. Ama-Diatoms angomunye wabalingisi bokuqala ukuvela emhlabeni, abahlala emanzini olwandle noma emanzini echibi. Yile-diatom enikeza umoya-mpilo emhlabeni nge-photosynthesis futhi ikhuthaza ukuzalwa kwabantu, izilwane nezitshalo.
