Chinhu chikuru che diatomite semutakuri weSiO2. Semuenzaniso, iyo inoshanda chikamu cheindasitiri vanadium catalyst ndeye V2O5, iyo cocatalyst ndeye alkali metal sulfate, uye mutakuri anonatswa diatomite. Mhedzisiro yacho inoratidza kuti SiO2 ine inodzikamisa mhedzisiro pazvinhu zvinoshanda, uye inowedzera nekuwedzera kweK2O kana Na2O yemukati. Chiitiko cheiyo catalyst chakabatanawo nekupararira kwerutsigiro uye chimiro chepore. Mushure mekurapa diatomite neasidhi, iyo oxide yekusachena yemukati inodzikira, SiO2 yemukati inowedzera, chaiyo nzvimbo uye pore vhoriyamu inowedzera, saka iyo inotakura mhedzisiro yediatomite yakanatswa iri nani pane iyo yakasikwa diatomite.

Diatomite inowanzoumbwa kubva kune zvakasara zvesilicates mushure mekufa kwe-single-celled algae, pamwe chete inonzi diatoms, uye inonyanya hydrated amorphous SiO2. Diatoms inogona kugara mumvura yakachena uye ine munyu. Kune akawanda marudzi emadiatoms, ayo anogona kazhinji kukamurwa kuva "middle mind" diatoms uye "feather striata" diatoms. Mune yega yega, kune akawanda "genera", ayo akaomarara.

Chinhu chikuru cheyakasikwa diatomite iSiO2. Iyo yepamusoro-soro diatomite ichena, uye SiO2 yemukati inowanzopfuura 70%. Single diatoms haina ruvara uye yakajeka, uye ruvara rwe diatomite rwunotsamira pamaminerari evhu uye organic zvinhu, nezvimwewo, uye kuumbwa kwe diatoms kubva kwakasiyana mineral sources kwakasiyana.

Diatomite ifossil diatomite deposit yakaumbwa mushure menguva yekuunganidza inosvika zviuru gumi kusvika kumakore makumi maviri mushure mekufa kwezvinomera zvine sero rimwe zvinonzi diatoms. Diatoms ndeimwe yeprotozoa yekutanga kuoneka paPasi, inogara mumvura yegungwa nemumadziva. Ndiyo diatom iyi, inopa oxygen kupasi kuburikidza nephotosynthesis, iyo inokonzera kuberekwa kwevanhu nemhuka nemiti.

Rudzi urwu rwe diatomite runoumbwa nekuiswa kwemasara eimwe-sero remvura yechirimwa diatomite. Iyo yakasarudzika pfuma yediatomite ndeyekuti inokwanisa kutora iyo yemahara silicon mumvura kuti igadzire skeleton yayo. Kana hupenyu hwayo hwapera, inogona kuisa uye kugadzira diatomite dhipoziti pasi pemamwe mamiriro e geological. Iyo ine zvimwe zvakasarudzika zvimiro, senge porosity, yakaderera kudzika, iyo yakakura chaiyo nzvimbo, hukama incompressibility uye kugadzikana kwemakemikari, kuburikidza nekutanga kudzvanya ivhu, kurongedza, calcination, senge kuyerera kwemhepo, kune yakaoma kugadzirisa nzira yekushandura yayo particle size kugovera uye pamusoro pezvivakwa, inokodzera kupfekedzwa pendi additives, uye zvimwe zvinodiwa mumaindasitiri.
