Diatomite wani nau'in dutse ne na siliceous, wanda galibi yake yaɗuwa a China, Amurka, Japan, Denmark, Faransa, Romania da sauran ƙasashe. Dutse ne mai siliceous sedimentary, wanda galibi ya ƙunshi ragowar tsoffin diatoms. Sinadarin sa galibi SiO2 ne, wanda za'a iya bayyana shi azaman SiO2 · nH2O, kuma ma'adinan sa shine opal da nau'ikan sa. Tanadin diatomite a China ya kai tan miliyan 320, kuma tanadin da ake tsammanin ya kai tan biliyan 2.

Yawan diatomite shine 1.9-2.3g/cm3, yawan girman shine 0.34-0.65g/cm3, takamaiman yankin saman shine 40-65 ㎡/g, kuma girman rami shine 0.45-0.98m ³/g. Shakar ruwa sau 2-4 na girmansa, kuma wurin narkewa shine 1650C-1750 ℃. Ana iya ganin tsarin ramuka na musamman a ƙarƙashin na'urar hangen nesa ta lantarki.

Diatomite ya ƙunshi SiO2 mara tsari kuma yana ɗauke da ƙaramin adadin Fe2O3, CaO, MgO, Al2O3 da ƙazanta na halitta. Diatomite yawanci rawaya ce mai haske ko launin toka mai haske, mai laushi, mai laushi da haske. Sau da yawa ana amfani da shi a masana'antu azaman kayan rufe zafi, kayan tacewa, cikawa, kayan gogewa, kayan da aka yi amfani da su a gilashin ruwa, wakilin canza launi, taimakon tace diatomite, mai ɗaukar abubuwan kara kuzari, da sauransu. Babban ɓangaren diatomite na halitta shine SiO2. Diatomite mai inganci fari ne, kuma abun da ke cikin SiO2 sau da yawa ya wuce 70%. Diatom ɗin Monomer ba su da launi kuma suna da haske. Launin diatomite ya dogara da ma'adanai na yumbu da kwayoyin halitta, da sauransu. Tsarin diatomite daga ma'adanai daban-daban ya bambanta.

Diatomite wani nau'in ƙasa ne da ke taruwa da ƙwayoyin halitta na diatom wanda aka samar bayan mutuwar wata shuka mai ƙwayoyin halitta guda ɗaya da ake kira diatom bayan taruwar kimanin shekaru 10,000 zuwa 20,000. Diatom yana ɗaya daga cikin farkon ƙwayoyin halitta a duniya, yana rayuwa a cikin ruwan teku ko ruwan tafki.

Ana samar da wannan diatomite ta hanyar ajiye ragowar diatom na tsire-tsire masu ƙwayoyin halitta guda ɗaya. Babban aikin wannan diatom shine yana iya shanye silicon kyauta a cikin ruwa don samar da kwarangwal ɗinsa.
