Chinhu chikuru chepasi diatomaceous semutakuri iSiO2. Semuenzaniso, chikamu chinoshanda cheindasitiri vanadium catalyst iV2O5, mutsigiri ndeye alkali metal sulfate, uye mutakuri anonatswa diatomaceous pasi. Ongororo dzinoratidza kuti SiO2 ine simba rekudzikamisa pazvikamu zvinoshanda, uye inosimbisa nekuwedzera kweK2O kana Na2O zvinyorwa. Chiitiko cheiyo catalyst chakabatanawo nekupararira kwepore chimiro checarr

ier. Mushure mokunge diatomite inobatwa neasidhi, iyo oxide yakasvibiswa yakaderedzwa, iyo SiO2 inowedzerwa, uye iyo chaiyo nzvimbo uye pore volume inowedzerawo. Naizvozvo, iyo inotakura mhedzisiro yeyakanatswa diatomite iri nani pane iyo yakasikwa diatomite.

Diatomaceous pasi rinowanzo umbwa nemasara esilicate mushure mekufa kweimwe-sero algae pamwe chete inonzi diatoms, uye musimboti wayo imvura-ine amorphous SiO2. Diatoms inogona kurarama mumvura yakachena uye mumvura ine munyu. Kune marudzi akawanda e diatom. Kazhinji, vanogona kukamurwa kuva "central order" diatoms uye "pinnacle order" diatoms. Mune yega yega, kune akawanda "genus", ayo akaoma kunzwisisa.

Chinhu chikuru chepasi diatomaceous pasi iSiO2, yepamusoro-soro machena, uye zvinyorwa zveSiO2 zvinowanzopfuura 70%. Monomer diatoms haina ruvara uye yakajeka. Ruvara rwepasi diatomaceous rinoenderana nevhu zvicherwa uye organic zvinhu. Kuumbwa kwe diatoms pane zvakasiyana-siyana zvicherwa zvakasiyana.

Diatomaceous earth ifossilized diatomaceous earth deposit yakaumbwa mushure mekufa kwechirimwa chine sero rimwe chete chinonzi diatom mushure menguva yekuunganidza makore angangoita 10 000 kusvika 20,000. Diatoms ndeimwe yevaratidziri vekutanga kuoneka panyika, vachigara mumvura yegungwa kana yegungwa. Ndiyo diatom iyi inopa oxygen kupasi kuburikidza nephotosynthesis uye inokurudzira kuberekwa kwevanhu, mhuka nezvirimwa.
