Chigawo chachikulu cha dziko la diatomaceous monga chonyamulira ndi SiO2. Mwachitsanzo, chigawo chogwira ntchito cha mafakitale vanadium chothandizira ndi V2O5, wolimbikitsa ndi alkali zitsulo sulfate, ndipo chonyamulira ndi woyengedwa diatomaceous lapansi. Kuyesera kumasonyeza kuti SiO2 imakhala ndi mphamvu yokhazikika pazigawo zogwira ntchito, ndipo imalimbitsa ndi kuwonjezeka kwa K2O kapena Na2O. Ntchito ya chothandizira imakhudzananso ndi kufalikira kwa pore kapangidwe ka carr

ndi. Pambuyo pothandizidwa ndi diatomite ndi asidi, zonyansa za oxide zimachepetsedwa, zomwe zili ndi SiO2 zimachulukitsidwa, ndipo malo enieni komanso kuchuluka kwa pore kumawonjezekanso. Chifukwa chake, chonyamulira cha diatomite choyengedwa bwino kuposa cha diatomite chachilengedwe.

Dziko lapansi la Diatomaceous nthawi zambiri limapangidwa ndi zotsalira za silicate pambuyo pa imfa ya algae yokhala ndi selo imodzi yomwe imatchedwa diatoms, ndipo tanthauzo lake ndi madzi okhala ndi amorphous SiO2. Ma diatomu amatha kukhala m'madzi abwino komanso amchere. Pali mitundu yambiri ya diatomu. Nthawi zambiri, amatha kugawidwa mu "central order" diatoms ndi "pinnacle order" diatoms. Mu dongosolo lililonse, pali "genus" yambiri, yomwe ndi yovuta kwambiri.

Chigawo chachikulu cha chilengedwe cha diatomaceous lapansi ndi SiO2, apamwamba kwambiri ndi oyera, ndipo zomwe zili mu SiO2 nthawi zambiri zimaposa 70%. Ma diatomu a monomer ndi opanda mtundu komanso owonekera. Mtundu wa dziko la diatomaceous umadalira mchere wadongo ndi zinthu zamoyo. Kapangidwe ka diatoms pamitundu yosiyanasiyana yamchere ndi yosiyana.

Dziko la Diatomaceous lapansi ndi gawo lachilengedwe la diatomaceous lapansi lomwe limapangidwa pambuyo pa kufa kwa chomera chokhala ndi selo imodzi chotchedwa diatom patatha zaka pafupifupi 10,000 mpaka 20,000. Ma Diatom ndi amodzi mwa owonetsa koyamba kuwonekera padziko lapansi, akukhala m'madzi a m'nyanja kapena m'madzi a m'nyanja. Ndi diatomu iyi yomwe imapereka mpweya kudziko lapansi kudzera mu photosynthesis ndikulimbikitsa kubadwa kwa anthu, nyama ndi zomera.
