I-Diatomaceous earth uhlobo lwedwala le-siliceous elisakazwa kakhulu emazweni afana ne-China, i-United States, i-Japan, i-Denmark, i-France, i-Romania, njll. Liyidwala le-siliceous sedimentary elenziwe ngezinto ezisele zama-diatom asendulo. Ukwakheka kwamakhemikhali alo ikakhulukazi yi-SiO2, okungamelwa yi-SiO2 · nH2O, kanti ukwakheka kwamaminerali alo kuyi-opal kanye nezinhlobo zalo. Izindawo zokugcina zomhlaba we-diatomaceous e-China zingamathani ayizigidi ezingu-320, kanye nendawo yokugcina engaba khona yamathani angaphezu kwezigidigidi ezimbili, ikakhulukazi e-East China naseNyakatho-mpumalanga ye-China. Phakathi kwazo, i-Jilin (54.8%, kanye neLinjiang City eSifundazweni saseJilin ebalwa njengezindawo zokugcina zokuqala eziqinisekisiwe e-Asia), i-Zhejiang, i-Yunnan, i-Shandong, i-Sichuan, nezinye izifundazwe zinokusatshalaliswa okubanzi, kodwa inhlabathi esezingeni eliphezulu igxile kuphela endaweni yase-Changbai Mountain e-Jilin, kanti iningi lamanye amaminerali liyinhlabathi yebanga lesi-3-4. Ngenxa yokuqukethwe okuphezulu kokungcola, ayikwazi ukucutshungulwa futhi isetshenziswe ngqo. Ingxenye eyinhloko yomhlaba we-diatomaceous njengomthwali yi-SiO2. Isibonelo, ingxenye esebenzayo ye-industrial vanadium catalyst yi-V2O5, i-co catalyst yi-alkali metal sulfate, kanti i-carrier iyi-diatomaceous earth ecwengisisiwe. Ukuhlolwa kubonise ukuthi i-SiO2 inomphumela wokuzinza ezingxenyeni ezisebenzayo futhi iyanda ngokwanda kokuqukethwe kwe-K2O noma i-Na2O. Umsebenzi we-catalyst uhlobene nokuhlakazeka kanye nesakhiwo se-pore ye-carrier. Ngemva kokwelashwa nge-asidi ye-diatomaceous earth, okuqukethwe kokungcola kwe-oxide kuyancipha, okuqukethwe kwe-SiO2 kuyanda, futhi indawo ethile yobuso kanye nevolumu ye-pore nakho kuyakhula. Ngakho-ke, umphumela we-carrier we-diatomaceous earth ecwengisisiwe ungcono kunowomhlaba we-diatomaceous wemvelo.

I-Diatomaceous earth ngokuvamile yakhiwa ngezinsalela ze-silicate ngemva kokufa kwe-algae eneseli elilodwa, eyaziwa ngokuthi ama-diatoms, futhi ingqikithi yayo iyi-aqueous amorphous SiO2. Ama-Diatoms angaphila emanzini ahlanzekile namanzi anosawoti, ngezinhlobo eziningi. Ngokuvamile angahlukaniswa ngama-diatoms “e-central order” kanye nama-diatoms “e-feathered order”, futhi i-oda ngalinye linezinhlobo eziningi “zesizukulwane” eziyinkimbinkimbi kakhulu.

Ingxenye eyinhloko yomhlaba we-diatomaceous wemvelo yi-SiO2, enekhwalithi ephezulu enombala omhlophe kanye nokuqukethwe kwe-SiO2 okuvame ukwedlula u-70%. Ama-diatoms ayedwa awanombala futhi acacile, futhi umbala womhlaba we-diatomaceous uncike kumaminerali obumba kanye nezinto eziphilayo. Ukwakheka komhlaba we-diatomaceous ovela emithonjeni ehlukene yamaminerali kuyahlukahluka.

I-Diatomaceous earth, eyaziwa nangokuthi i-diatom, iyi-fossilized diatom deposit eyakheka ngemva kokufa kwesitshalo esisodwa esineseli kanye nesikhathi sokubekwa kwayo esiyiminyaka engaba ngu-10000 kuya ku-20000. Ama-Diatoms ayengenye yezinto eziphilayo zokuqala ukuvela eMhlabeni, ezihlala emanzini olwandle noma emanzini echibi.

Lolu hlobo lomhlabathi we-diatomaceous lwakhiwa ngokubeka izinsalela ze-diatoms zezitshalo zasemanzini ezineseli elilodwa. Ukusebenza okuyingqayizivele kwale diatom ukuthi ingamunca i-silicon yamahhala emanzini ukuze yakhe amathambo ayo. Lapho impilo yayo iphela, ibeka futhi yakhe izinsalela zomhlabathi we-diatomaceous ngaphansi kwezimo ezithile zejiyoloji. Inezakhiwo ezithile ezihlukile, njenge-porosity, ukuhlushwa okuphansi, indawo enkulu ethile yobuso, ukungacindezeleki okulinganiselwe, kanye nokuqina kwamakhemikhali. Ngemva kokushintsha ukusatshalaliswa kosayizi wezinhlayiya kanye nezakhiwo zobuso bomhlabathi wokuqala ngokusebenzisa inqubo.Izinqubo zokuhlola ezifana nokuchoboza, ukuhlunga, ukugaya, ukuhlukaniswa komoya, kanye nokususwa kokungcola, ingafanelekela izidingo ezahlukahlukene zezimboni ezifana nokugqoka kanye nezithasiselo zopende.
