I-Diatomiteiwuhlobo lwetshe le-siliceous, elihlakazeke kakhulu eChina, e-United States, eDenmark, eFrance, eRomania nakwamanye amazwe. Iwuhlobo lwetshe le-biogenic siliceous accumulation rock, elakhiwe ikakhulukazi izinsalela zama-diatoms asendulo. Ukwakhiwa kwamakhemikhali ayo ngokuyinhloko yi-SiO2, engamelwa yi-SiO2 · nH2O, futhi ukwakheka kwamaminerali kuyi-opal kanye nezinhlobonhlobo zayo.

I-China inamathani ayizigidi ezingama-320umhlaba we-diatomaceousizindawo ezigciniwe kanye namathani angaphezu kwezigidigidi ezi-2 ezinqolobane ezilindelekile, ezigxile kakhulu eMpumalanga China naseNyakatho-mpumalanga yeChina. Phakathi kwazo, uhla likhulu uma kuqhathaniswa, kanti iJilin inezinqolobane ezengeziwe (54.8%, lapho izinqolobane ezifakazelwe zeLinjiang City, i-akhawunti yeSifundazwe saseJilin i-Asia.), Zhejiang, Yunnan, Shandong, Sichuan nezinye izifundazwe, nakuba zisakazwa kabanzi, kodwa inhlabathi esezingeni eliphakeme igxilwe kuphela endaweni yaseChangbai Mountain ye-Jilin grade 3, futhi iningi lama-deposit grade 3. Ngenxa yokuqukethwe ukungcola okuphezulu, azikwazi ukucutshungulwa ngokuqondile futhi zisetshenziswe. Ukwakheka kwamakhemikhali e-diatomite ngokuyinhloko yi-SiO2, equkethe inani elincane le-Al2O3, Fe2O3, CaO, MgO, njll. kanye ne-organic matter. Iqukethe inani elincane le-Al2O3, Fe2O3, CaO, MgO, K2O, Na2O, P2O5 kanye ne-organic matter. I-SiO2 ivamise ukubala ngaphezu kuka-80%, kuze kufike ku-94%. Okuqukethwe kwe-iron oxide yekhwalithi ephezulu ye-diatomaceous earth ngokuvamile ingu-1 ~ 1.5%, kanti okuqukethwe kwe-alumina kungu-3~6%. Ukwakhiwa kwamaminerali kwe-diatomite ikakhulukazi i-opal kanye nezinhlobonhlobo zayo, kulandelwa amaminerali obumba-i-hydromica, i-kaolinite ne-mineral detritus. Imfucumfucu yamaminerali ihlanganisa i-quartz, i-feldspar, i-biotite kanye ne-organic matter. Okuqukethwe kwe-organic kusuka kumanani okulandela umkhondo kuye ngaphezu kwama-30%. Umbala womhlaba we-diatomaceous umhlophe, umhlophe, umpunga kanye nokukhanya okumpunga-nsundu, njll. Unezici zokulula, ukuxega, isisindo esilula, i-porosity, ukumuncwa kwamanzi kanye nokungena okuqinile. Iningi le-silica ye-diatomite ayiyona i-crystalline, futhi okuqukethwe kwe-silicic acid encibilikayo ku-alkali ngu-50 ~ 80%. I-Amorphous SiO2 iba yikristalu uma ishisiswe ibe ngu-800~1000°C, futhi i-asilicic acid encibilikayo ku-alkali ingancishiswa ibe ngu-20~30%.

Umhlaba we-Diatomaceousayinabo ubuthi, kulula ukuyihlukanisa nokudla, futhi ingasetshenziswa futhi ngemva kokuhlukana. Kuye kwaqashelwa ochwepheshe abaningi bokulawula izinambuzane njengento ebulala izinambuzane. Isizathu sokuthi kungani umhlaba we-diatomaceous ungavimbela izinambuzane ukuthi lapho izinambuzane zikhasa ekudleni okuxubene nomhlaba we-diatomaceous, umhlaba we-diatomaceous uzonamathela ebusweni bomzimba wezinambuzane, ubhubhise ungqimba lwe-waxy lwe-epidermis yezinambuzane nezinye izakhiwo ezingenamanzi, futhi zibangele umzimba wezinambuzane. Ukulahlekelwa amanzi kuholela ekufeni. I-Diatomaceous Earth kanye neziqephu zayo nazo zingasetshenziswa njengezibulala-zinambuzane nezibulala-khula ezinsimini zezithelo. Izinhlayiya ze-Diatomaceous Earth zingasatshalaliswa emoyeni noma zigqitshwe emhlabathini ukuze zikhangise futhi zibulale ezinye izinambuzane. I-Diatomaceous Earth ingasetshenziswa njengesithwali esihle kakhulu kanye ne-ejenti yokunamathela kumanyolo wamakhemikhali. Ama-micropores angaphezulu komhlaba we-diatomaceous angamunca futhi asonge ngokulinganayo umanyolo wamakhemikhali ukugwema ukupakishwa okuvulekile kwesikhathi eside kanye nokumuncwa komswakama kanye nokuhlangana. Iqukethe 60-80% diatoms. Umanyolo omusha we-biochemical onobungane nemvelo onomhlaba kanye nenani elincane lezitshalo ezincane ze-microbial zingathuthukisa umsebenzi wokuzivikela wesitshalo ngokwawo, ukhuthaze ukukhula kwezitshalo, futhi uthuthukise inhlabathi ngokwayo ukuze ufeze inhloso yokunciphisa inani likamanyolo ovamile nezibulala-zinambuzane ngo-30-60% ngesikhathi sokukhula kwezitshalo.
