Diatomite idombo remhando ye siliceous, rinonyanya kupararira muChina, United States, Japan, Denmark, France, Romania nedzimwe nyika. Idombo re siliceous sedimentary rine biogenic, rinonyanya kuumbwa nemasara e diatoms ekare. Makemikari aro anonyanya kuumbwa neSiO2, iyo inogona kuratidzwa seSiO2 · nH2O, uye mineral yaro iopal uye mhando dzaro. Matura e diatomite muChina anosvika mamiriyoni mazana matatu nemakumi maviri ematani, uye matura anotarisirwa anosvika mabhiriyoni maviri ematani.

Kuwanda kwe diatomite i1.9-2.3g/cm3, kuwanda kwehuwandu i0.34-0.65g/cm3, nzvimbo chaiyo yekumusoro i40-65 ㎡/g, uye vhoriyamu yepore i0.45-0.98m³/g. Kunyudzwa kwemvura kunopfuura ka2-4 kupfuura huwandu hwayo, uye poindi yekunyunguduka i1650C-1750 ℃. Chimiro chakakosha chepore chinogona kuonekwa pasi pemaelektron microscope.

Diatomite inoumbwa neSiO2 isina chimiro uye ine huwandu hushoma hweFe2O3, CaO, MgO, Al2O3 uye tsvina yeorganic. Diatomite inowanzova yero yakajeka kana grey yakapfava, yakapfava, ine maburi uye yakareruka. Inowanzoshandiswa mumaindasitiri sezvinhu zvinodzivirira kupisa, zvinhu zvekusefa, zvinozadza, zvinhu zvinogumbura, zvinhu zvisina kuchena zvegirazi remvura, zvinobvisa ruvara, diatomite filter aid, catalyst carrier, nezvimwewo. Chinhu chikuru che diatomite yechisikigo iSiO2. Diatomite yemhando yepamusoro ichena, uye huwandu hweSiO2 hunowanzo pfuura 70%. Monomer diatom haina ruvara uye inoonekera. Ruvara rwediatomite runoenderana nemaminerari evhu nezvinhu zveorganic, nezvimwewo. Kuumbwa kwediatomite kubva kune zvakasiyana zvicherwa kwakasiyana.

Diatomite imhando yefossil diatom accumulative ivhu rakaunganidzwa mushure mekufa kwechirimwa chine sero rimwe chete chinonzi diatom mushure menguva yekuungana kwemakore angangoita chiuru kusvika zviuru zviviri. Diatom ndeimwe yeprotozoa yekutanga panyika, inogara mumvura yegungwa kana mumvura yedziva.

Iyi diatomite inoumbwa nekuiswa kwezvisaririra zvediatom yemumvura ine sero rimwe chete. Kushanda kwakasiyana kweiyi diatom ndekwekuti inogona kupinza silicon yakasununguka mumvura kuti igadzire skeleton yayo. Kana hupenyu hwayo hwapera, inoisa uye inoumba madhiragi ediatomite pasi pemamwe mamiriro epasi. Ine zvimwe zvinhu zvakasiyana, zvakaita sekukombama, kuzara kwakaderera, nzvimbo yakakura chaiyo, kusagadzikana uye kugadzikana kwemakemikari. Mushure mekuchinja kugoverwa kwehukuru hwezvimedu uye hunhu hwepamusoro hwevhu risina kubikwa kuburikidza nekukuya, kurongedza, calcination, kupatsanurwa kwemhepo, kubviswa kwetsvina uye mamwe maitiro ekugadzirisa, inogona kushandiswa kune zvakasiyana-siyana zvinodiwa zveindasitiri zvakaita sekuwedzera pendi.
