Diatomite ke mofuta oa majoe a siliceous, a ajoang haholo Chaena, United States, Japane, Denmark, Fora, Romania le linaheng tse ling.Ke lefika la biogenic siliceous sedimentary, haholo-holo le entsoeng ka mesaletsa ea li-diatoms tsa khale.Sebopeho sa eona sa lik'hemik'hale ke haholo-holo SiO2, e ka hlalosoang e le SiO2 · nH2O, 'me motsoako oa eona oa liminerale ke opal le mefuta ea eona.Libaka tsa polokelo ea diatomite Chaena ke lithane tse limilione tse 320, 'me mehloli e lebelletsoeng e feta lithane tse limilione tse likete tse peli.

Boima ba diatomite ke 1.9-2.3g/cm3, bongata bo bongata ke 0.34-0.65g/cm3, sebaka se ikhethileng ke 40-65 ㎡/g, 'me bophahamo ba pore ke 0.45-0.98m ³/ g.Ho kenngoa ha metsi ke makhetlo a 2-4 a bophahamo ba oona, 'me ntlha ea ho qhibiliha ke 1650C-1750 ℃.Sebopeho se khethehileng sa porous se ka bonoa tlas'a microscope ea elektronike.

Diatomite e entsoe ka amorphous SiO2 mme e na le palo e nyane ea Fe2O3, CaO, MgO, Al2O3 le litšila tsa tlhaho.Diatomite hangata ke mosehla o mosehla kapa o mosehla o bobebe, o bonolo, o na le masoba le bobebe.Hangata e sebelisoa indastering e le thepa ea ho kenya mocheso, lisebelisoa tsa ho hloekisa, li-filler, li-abrasive, lisebelisoa tse tala tsa khalase ea metsi, li-decolorizing agent, diatomite filter aid, catalyst carrier, joalo-joalo Karolo e ka sehloohong ea diatomite ea tlhaho ke SiO2.Diatomite ea boleng bo holimo e tšoeu, 'me litaba tsa SiO2 hangata li feta 70%.Li-diatom tsa monomer ha li na mebala ebile lia pepenene.'Mala oa diatomite o itšetlehile ka liminerale tsa letsopa le lintho tse phelang, joalo-joalo Sebopeho sa diatomite se tsoang mehloling e fapaneng ea liminerale se fapane.

Diatomite ke mofuta oa "fossil diatom accumulative deposit" e entsoeng ka mor'a lefu la semela se nang le sele e le 'ngoe se bitsoang diatom kamora nako ea ho bokellana ea lilemo tse ka bang 10000 ho isa ho tse 20000.Diatom ke e 'ngoe ea li-protozoa tsa khale ka ho fetisisa lefatšeng, tse phelang metsing a leoatle kapa metsing a letša.

Diatomite ena e thehoa ke ho behoa ha masalla a diatom ea semela sa metsing se nang le sele e le 'ngoe.Ts'ebetso e ikhethang ea diatom ena ke hore e khona ho monya silicon e sa lefelloeng ka metsing ho etsa skeleton ea eona.Ha bophelo ba eona bo felile, e tla beha le ho theha diatomite deposits tlas'a maemo a itseng a jeoloji.E na le thepa e ikhethang, joalo ka porosity, mahloriso a tlase, sebaka se seholo se ikhethileng, ho se tsitse ha lik'hemik'hale le botsitso ba lik'hemik'hale.Ka mor'a ho fetola boholo ba likaroloana le thepa ea holim'a mobu o tala ka ho sila, ho hlophisa, ho bala, ho arola moea, ho tlosa litšila le mekhoa e meng ea ts'ebetso, e ka sebelisoa ho litlhoko tse fapaneng tsa indasteri tse kang li-additives tsa pente.
